You get better performance and reliability without the emission-related issues of older models. This engine is often seen as the best Duramax model after emission controls were added. Better emission controls in the L5P Duramax engine, introduced in 2017, have made it perform better and last longer. Regular upkeep ensures your L5P engine works well and avoids potential problems. Even though MAP sensor issues are relatively minor, they can still affect your vehicle’s performance if ignored. You hear zero clatter for the diesel engine. About the time the truck when back I was almost used to it. You’d be hard-pressed to tell at startup or even under acceleration that you are driving a diesel-based on engine noise. Chevrolet Tahoe 4WD Premier: By the Numbers The Mach 1 64mm turbo was slower than the STR, but was still able to spool 7.5% faster than stock, even though it has a notably larger rotating assembly.However, this is certainly something to consider if you have a high-performance truck.In real-world terms, the Power Stroke provides confident passing power and minimal turbo lag for its size.However, any additional power is going to take a toll on your transmission, whether it’s just a modest tune or a heavily modified engine.The Duramax engine has a displacement of 6.6 liters and produces more than 300 horsepower and 520 pound-feet of torque.In the 6.7L Cummins engine, raw fuel is released into each cylinder during the exhaust stroke, after normal combustion has occurred. Both engines hook up to an Allison 10-speed automatic transmission and either rear- or four-wheel drive; each is compatible with the single or dual rear-wheel axle. The Silverado 2500HD and 3500HD have a standard gas-powered 6.6-liter V-8 that makes 401 horsepower and 464 pound-feet of torque. Both engines come with a 10-speed automatic transmission, rear- or four-wheel drive, and single or dual rear-axle setups. Both of these issues result in fuel leaking from the injector which can then enter the crankcase.All it takes is a rock or a tree root pushed up by the tire, and the fuel filter or water separator can be damaged.Combined with all new Bosch CP4.2 common rail injection and a modified turbocharger, this new engine is the first of its kind to reach the 1,000 lb.-ft.This is the pickup you pick up when you need to live the real-deal truck-stuff life, pulling horse trailers or assembling lumber to raise a whole barn.It’s engineered with features that make it a contender for any homeowner looking to protect their investment.Want to learn more about the latest insights in the diesel industry?Sure, diesel comes with a few drawbacks, such as the higher price of entry and the need to refill the DEF tank from time to time.Check out that earlier review if you’re looking for a comprehensive rundown of the truck—today, we’re going to dig into just what makes the diesel Tahoe so great.It could happen at any time unless you dig into the engine and eliminate the possibility—but it probably won’t. If you’re really looking for something with a lot of power though, look no further than the 12000EH, which has a total of 12,000 starting watts, and 9500 running watts. For something with a little less power, you’ll like the Duromax xp4850EH, which has about half the power of the 10000E. This makes this bulky generator perfect for construction sites and other high-power situations. You have an impressive power output with the 10000E, with 8000 running watts and 10,000 peak wattage. The control panel also features oil warning light and circuit breaker. If your truck is only overheating under extremely heavy loads, that is generally more normal. Overheating issues are more common on LB7 and LLY Duramax trucks than future generations. Depending on your truck’s mileage, you should also consider replacing nearby parts like the water pump housing, or even the thermostat. This causes various performance issues, hard starts, and even engine codes. Due to their reputation for strength and longevity, Duramax diesel engines are a favorite among truck enthusiasts. Like every generation of this transmission that came before it, the factory Allison can’t handle everything the factory injectors, high-pressure fuel pump and turbocharger can throw at it. All modern diesels are beasts, but the L5P Duramax in GM’s ’17-present heavy-duty trucks is exceptional. If they did, folks would clearly see the fuel-efficiency advantage offered by diesels over gasoline engines. The federal government does not publish official fuel economy estimates for heavy-duty pickup trucks. The Cummins ITB 6.7L engine However, with tuning the gains from an intake are amplified and produce solid power gains while also taking a bit of stress off of the engine and turbo.If peak performance is what you want out of your L5P then the turbo and intake are both limiting factors that will need to be upgraded.The regen process puts backpressure on the engine which can lead issues with the cooling system, fueling system, etc.This injection pump is drastically different than the Bosch units found on older trucks.There are several aftermarket welded water pumps available.So as all-purpose as possible, whether your L5P is towing your toys, hauling your utility trailer, or even just daily driving, PPEI recommends that you do not exceed a towing capacity of 15,000lbs.My only concern about this engine package is my perceived lack of service access.If you experience head gasket failure on your LLY Duramax, it’s probably best to take your truck to a shop.If your truck is only overheating under extremely heavy loads, that is generally more normal. Here’s a chart depicting each of the different power levels and their respective performance gains. I’ve done everything from heavy towing, long road trips, driving in the mountains and even consistent idling for my day job with this tuner. These trucks came equipped from the factory with an almost impenetrable ECU that makes tuning these vehicles extremely difficult. The company released the first engine in 2001, which was a 6.6-liter V8 engine.Some of this could be attributed to my chronic smashing of the accelerator pedal because the higher tunes just make driving the truck so much more fun.Blown head gaskets, water pump failure, fan clutch failure, and even a dirty or clogged radiator can be the root cause of your overheating issues.Thus I’m looking at the Silverado 1500 diesel as something I’d actually buy, considering the likely deals to be made in the current environment.Now that these trucks no longer have factory warranty, your best option to fix leaking transmission cooling lines is to upgrade to aftermarket lines.The latest Powerstroke engines feature a more straightforward design and ease of maintenance.So, many Duramax owners report that their engines have easily passed the 200,000 mile mark with few major problems.To reduce NOx emissions, the crankcase ventilation system went from an open to closed loop. The higher density polyurethane foam provides excellent compressive strength for heavy vertical loads. For superior thermal performance in cold climates,Trusscore is likely the better choice. After comparing these two brands across structural performance, cost, installation, and ideal applications, which comes out ahead? And their higher upfront cost results in superior building performance. The bulkhead fitting on top has two ports, one for the suction tube, and the other for a return line from the lift pump, and when its mounted, the fuel lines are hidden from view, making for a much cleaner and safer installation. Most fuel sumps have at least a 1/2” port to support the flow demands of a larger aftermarket lift pump, and usually the external fuel line is run below the tank. The pickup point is now lower than the bottom of the tank, so no matter how low your fuel level gets, the pump always will draw in fuel. This problem is exaggerated when running a lift pump with a higher flow rate, since the pump is constantly recirculating fuel in and out of the tank. It continues to make 445 horsepower and 910 lb-ft, but now it hooks up to an Allison 10-speed automatic. We'd also add four-wheel drive and the refined Duramax diesel powertain to the LT trim level. While neither GM truck is the best heavy-duty pickup on the block, the Chevy will satisfy Bow Tie fans with its bold looks and big capabilities. The latter allows the Silverado HD to tow up to 35,500 pounds, and the truck's roster of innovative trailer-assistance features only make towing jobs easier. Each engine has unique features. In the end, test drive each truck. Each engine can serve you well. The pump is responsible for pushing the engine coolant throughout the cooling system to prevent the engine from overheating. However, one common failure point on tuned engines is cracked pistons. • Updated, more efficient variable geometry turbocharger (VGT, also variable vane or VVT) design reduced turbocharger lag and improved engine responsiveness. This latest version featured some upgraded internals and received a boost in power, now putting out 360 horsepower and 650 ft/lbs. Chevy and GMC truck maintenance, tuning, and performance modification guides However, these engines are still new and its potential has yet to be fully realized. With the engine upgrades, all signs are pointing to the L5P having strong tuning and performance potential. Since the EPA doesn't publish fuel-economy estimates for vehicles as heavy as the Sierra HD, we don’t have official numbers, but we have taken a diesel-powered Sierra 2500HD Denali on our real-world highway fuel-economy route. While their Ford Super Duty and Ram HD rivals boast higher tow ratings, these beasts are nonetheless capable, offering gas and diesel V-8 engines with oodles of torque to make hauling tasks easy. While an aftermarket fuel tank won’t give you more horsepower, it allows you to travel further distances and be picky about where you get your diesel from. There are numerous aftermarket additions that can increase horsepower, torque, fuel economy, or reliability without breaking the bank. Diesel engines have had to incorporate various emissions reduction equipment over the years to help reduce air-polluting NOx gasses. Fuel Sippers (Both) Contaminants could damage the pump, sending metal shavings circulating through the fuel system and ruining it, triggering a massive repair bill. The power increase came in spite of the LMM being the first Duramax subject to new diesel emissions regulations in the U.S., which came into effect on January 1, 2007. The LBZ featured many upgrades over the LLY, including a stronger engine block, beefier connecting rods, an improved fuel injection system, and a larger turbocharger intake. Chevy's decision to ship the engine with a restrictive turbo intake setup and small radiator gave the LLY a reputation for overheating when towing. Reasons Why You Shouldn't Delete Your L5P Duramax's DPF One problem can rear its head when you are pushing the power of the LMM to a level GM never imagined, and that’s with the pistons. Mechanically, the LMM Duramax is almost identical to the LBZ, and if you do a quick search of the web for LMM Duramax problems, you’ll find much like the earlier LBZ it had very few problems related to the engine itself. People often ask what is the best lift pump for an LBZ, and truthfully ANY lift pump is better than none at all. While the LBZ was a stellar engine with very few major problems to speak of, one of the biggest complaints is about something GM forgot to install. Since the LBZ lacked modern diesel emissions devices, it lived a very short life under the hoods of only a few GM vehicles.This tire combines the aggressive tread pattern of a mud-terrain tire with the on-road comfort of an all-terrain tire, offering versatile performance for both off-road adventures and daily driving.There is a general lack of harshness coming from any mechanical noises of the engine at all.This would cause a chain reaction that would then essentially destroy the whole fuel system and lead to $10,000+ of repairs.The high pressure water pump is 116 PSI, DuroMax semi-trash pumps are rated in gallons per minute and can be damaged if pressurized.All models are equipped with a 24-gallon fuel tank.LML was the longest running single generation of Duramax engine, and is denoted by engine code “8” in the vehicle identification number. The Edge Evolution CTS 2 offers moderate power gains at each power level. The custom tunes from GDP are excellent, many Duramax owners on the forums claim they're one of the best diesel tuners out there. With its many features and warranty friendliness, you can enjoy the performance enhancements without any drawbacks! The iDash monitor provides the driver with parameter information, performance testing, and the ability to diagnose issues. This kit helps protect your car’s fuel system. It is a smart choice for power when you need it most. They are built to last and keep you powered up. DuroMax makes top-quality dual-fuel generators. However, if you’re looking for more power and comfort, it’s not uncommon for packages to run north of $75,000, especially with the Silverado HD.Used, you’re still looking at $30,000 for base models. Anecdotally, there are reports of people getting nearly 500,000 miles out of their Duramax engines with regular maintenance. Has a littlebit of problem buying too many trucks. With my Cummins trucks the gauge always was always right in the middle, with very small directional changes according to my driving conditions/habits. But with this new motor, the truck has plenty of passing power. This, combined with the improvements over the LLY, makes it an incredibly desirable platform for the performance-minded enthusiast. The LBZ saw the first use of GM’s new E35 32-bit engine controller as well. High-pressure fuel rails and delivery lines were also revised, as was the glow plug system. Improvements to the fuel delivery system were implemented as well, with the adoption of a new injector design with seven-hole nozzles. First, the block casting and machining improved slightly in order to strengthen the bottom of the cylinder bores to better handle the increased power. If the latter, they sell the very popular Silverado 1500 full-size and the Colorado midsize trucks, which are highly capable in their own right and are more traditional in their design. Chevrolet is drawing a line in the sand about whether a customer wants a tough truck that can tow and haul heavy weights, or a merely “competent” truck. Even the bold front end differs from the Silverado 1500, so not to confuse which is the truly heavy-duty truck. At eight feet wide and nearly seven feet tall, this heavy-duty truck is both commanding and imposing. Continuing on with the stout bottom end accolades, both engines make use of forged-steel crankshafts and connecting rods. Ironically enough, the latest EcoDiesel V-6—with its CGI block, reworked aluminum heads and revamped fuel system—edges out the I-6 Duramax in peak torque (480 lb-ft vs. 460 lb-ft). Others, like long-term engine protection, are seen over time. Anyone with a Duramax diesel truck can use them. If you notice any of these symptoms, address the issue immediately to prevent engine damage. Early detection of cooling system issues can save you from costly repairs. A properly functioning thermostat ensures the engine stays within its optimal temperature range. Radiators and hoses are vulnerable to wear and tear, especially under heavy-duty use. They both make powerful diesel engines. With its 2025 updates, though, all Ram HD models get the “High Output” engine as the only diesel option, with 430 horsepower and 1,075 lb-ft on tap. We’ve also tested the latest generation Ford F-250 Super Duty with Ford’s 6.7-liter Power Stroke engine, putting out 500 horsepower and 1,200 lb-ft of torque. We drove both powertrains through mountains while towing several tons and were impressed by their capabilities. It continues to make 445 horsepower and 910 pound-feet, but now it hooks up to an Allison 10-speed automatic. We'd also add four-wheel drive and the refined Duramax diesel powertrain to the LT trim level. A lift pump helps maintain consistent fuel pressure, allowing the injection system to operate more efficiently. The 18,500-pound conventional trailer has a tongue weight of 1850 pounds, leaving much more breathing room to the truck's payload, though we can say without question we'd rather pull 18,000 pounds with a fifth wheel than a bumper simply because it is a more stable setup. The High Country is loaded with options and features that aren't on a bench-seat work truck, and all these extras contribute to the truck's payload. The pin-weight of a fifth wheel (15 percent of the trailer mass) actually bumps into the payload capacity of the truck, whereas the lower tongue weight of the bumper-pull hitch (10 percent of trailer mass) allows for a slightly higher trailer weight. While it is only a 400-pound difference, the tow-rating delta comes down to the payload of the truck. This High Country falls into a seldom visited canyon of the SAE towing practices. Upgrading the intake horn to a 3.5″ diameter steel pipe will increase air flow and therefore increase power.A range of engines—including a turbocharged four-cylinder, to a pair of V-8s, and a Duramax diesel 3.0-liter inline-six—means there's a Silverado 1500 powertrain for any job or adventure.Your stock filter head is retained, and no other modifications to the tank or rest of the fuel system are required.As the 6.7L engine was the first Cummins unit that uses variable geometry turbocharger, it is not unusual to have some initial problems.The flip side is that Ford and GM have extended service intervals due to larger oil capacities and advanced monitoring, so one could argue all three are equally reliable if maintained by the book.Pickup trucks have gotten massive and really this is where you see it.Look for products specifically designed for diesel engines and Duramax trucks.It is worth noting that DuroStar and DuroMax generators at higher power levels are often very similar besides a few tiny differences. If you don’t know what supporting mods you will need, or if it sounds a little above your head, stick with a drop-in replacement turbo! Without these supporting mods, an upgraded turbocharger will do you no good! You’re going to have to go with a significantly bigger turbo or a twin-turbo set-up. Here are some of our favorite “Drop-in” LB7 Duramax turbochargers. Unlike the standard turbo-four, the V-8 also lets us select the Z71 Off-Road package with a host of upgraded hardware that makes playing in the dirt and mud easier and more fun. The Silverado 1500 offers tons—literally—of towing capacity, more than the equivalent Ram 1500 and GMC Sierra 1500 offer. The larger gas V-8 is a staple and arguably one of the smoothest out there, but it doesn't overcome the fact that the Silverado's ride can become a bit too rough at times. The filter is isolated from high engine temperature by a heat shield designed to lower the temperature of the air entering the engine, which in-turn increases horsepower. The fully enclosed air box design helps to maintain the IAT (intake air temperature) close to ambient for consistent horsepower and torque. Since it was introduced in their smaller truck lineup, it’s been a very popular option because of its impressive performance and outstanding fuel economy. Traditional diesels like the 6.6L Duramax offered in GM’s heavy duty trucks are bigger, more expensive to own, and more expensive to operate. A leaking o-ring not only results in a fuel leak, but air can also enter the fuel system. For higher horsepower applications, you can purchase up to 160 gph or higher, all depending on your needs. They can greatly improve the life span of your fuel system components like injectors or your CP3 injection pump. Even in stock applications, this design is also more likely to encounter air in the fuel lines. For one, active regeneration of the DPF required fuel, which reduced fuel economy compared to the LBZ. The stricter regulations meant that the LMM shipped with a larger EGR system and a diesel particulate filter (DPF). After a couple of short-lived 6.6-liter Duramax revisions, GM finally stuck with a version of the engine for more than a couple of years. But if you're leaving it stock or running a more conservative tune, this is the pre-emissions Duramax to buy. L5P Duramax History & Model Year Changes But the redesign didn’t address any issues with the problematic EGR system nor the expensive cost and difficulty in servicing both the timing chain and oil pump belt. The fuel injector and oil belt changes were direct responses to common problems and maintenance issues with the LM2. Most of these had to due with expensive service and maintenance intervals caused by the timing chain and oil pump belt. It uses a single VGT turbocharger and common-rail fuel injection. GM released the 3.0 Duramax in 2019 in its half-ton Sierra and Silverado 1500 trucks. Traction was never going to be a problem and we powered up very easily in 4-wheel high. We headed out to the Laguna Mountains to a truck trail named Thing Valley Road, which winds its way south to a locked gate put in by the Border Patrol to prevent migrants circumventing the checkpoints. It’s not super quick from a standstill but the 0-60 time of 7.1 seconds is quick enough for most and it feels quicker driving it than the numbers suggest. The brakes feel solid and the steering offers a decent amount of weight and feedback, it’s only let down is its ride quality when driven over sharp undulations in the pavement. It also has a greener footprint pumping out way less CO2. The Duramax, with 10 gears and slightly less torque, often feels quicker and more responsive at highway passing speeds. The Cummins provides a very strong initial launch (that low-end torque again), but will rev out more slowly and shift earlier due to the 6-speed gearbox. Older iterations of Power Stroke (and earlier Ford diesels like the 6.0L or 7.3L) were louder, but the current generation is on par with the others in acoustic comfort. Each engine has its strengths and weaknesses. The seats are very comfortable, and my tester had the leather seat option for $985 and on the LT model, the drivers are powered. There wasn’t much of a luxury feel inside my LT tester, it’s functional but not particularly special, the quality of the plastics is inferior to the Ram, which I hate to keep saying. It all began in 2006 when the GMC Canyon and Chevrolet Colorado Midsize pickup models finally said “I do” and married the 2.8L Duramax engine, bringing it to American soil. In that case, you also need to be aware of the problems you might experience while using the 2.8L Duramax diesel engine. It’s also because the small diesel engine that can hit 27 MPG average qualifies it as the ideal choice for Colorado or Canyon owners. For pickup fans, the Chevy with the 2.8L Duramax diesel engine is considered a good engine. Diesel Power Products is your diesel performance headquarters proudly located in Spokane Valley, Washington. This makes it good for heavy-duty tasks. However, it has more torque, around 850 lb-ft. The 6.7 Cummins offers similar power. Leverage real-time analytics to gain comprehensive insights into individual student and classroom engagement and progress. With emoji reactions, your students can express confidence, confusion, curiosity, or excitement in real-time. An example of a scale factor is the ratio used on a model airplane to describe how much bigger the actual airplane is than the model. If it’s not desired, then simply reduce the fraction like you would normally. There are also engineering rules that are primarily used in civil engineering to scale measurements for roadways and land development. By deleting the factory emission system which has been suffocating your diesel, you’ll immediately notice a night and day difference. A gasoline-drinking 401-hp 6.6-liter V-8 is standard and is bolted to a six-speed automatic transmission. When it comes to moving mountains—or towing the enormous equipment that can—the Silverado 2500HD and 3500HD don’t take a lunch break. The engine got its high towing capacity thanks to its enormous torque. The engine was specifically designed for trucks but has been used both in trucks and vans since its release. Compared to other engines in the Colorado and Canyon lineup, the engine has an impressive fuel economy. Once you know how you are going to use the truck it is time to start learning the basics of how turbo's work. Buckle up — we're diving into the diesel war to see what makes each engine tick and why truck fans swear by their favorite. Engine technology has drastically improved in the last 20 years at the same time as emissions regulations have gotten stricter. And along the way the engine has become significantly more emissions friendly. Many buyers are reluctant to pick up a truck that's deleted given the fact they can face a fine or impound for not running the vehicle with factory emissions equipment. We often get calls from customers asking to purchase emission system components so they can sell their trucks back to a dealer. Do keep in mind though that some emissions system components, like most parts of the truck, will need to be maintained throughout the life of the truck. Please see your specific pressure washer manual under the "Maintenance schedule" section for more details on the required maintenance timeframes. No, bleach can cause internal damage to the pressure washers spray wand, hose, and pump seals. Our pressure washer models can use either 30W, 10W-30, or 5W-30 oil in synthetic or conventional depending on climate. The key switch can be separated from the engine by extending each of the color coded wires, and leading a ground wire from the bare metal on the key switch to the bare metal of the engine block. Specifications of ITB 6.7L Cummins This emissions system is separate of the exhaust-related emissions equipment and instead occurs before the exhaust.Over time this plastic wears down leading to water pump failure which commonly occurs every 80,000 to 100,000 miles.As you drive your diesel, the DPF captures the particulates which then are stored inside the DPF system.The problems start when you increase the horsepower output of the engine, since more horsepower is made by injecting more fuel.First off, it’s a beast when it comes to protecting your engine.Other tunes I’ve used in the past like EFI Live resulted in better fuel economy gains.The STR not only out-performed the stock unit in peak horsepower, but also carried 60 or more additional HP throughout a majority of the RPM range.Solving many of these problems will not only improve longevity and durability, but they can often improve performance too. Whether you’re towing heavy or building a performance rig, the LBZ is the one everyone wants, and resale values show it. With 360 hp and 650 lb-ft of torque, it delivered strong performance without the headaches of emissions equipment like DPFs. The LML strikes a sweet spot for buyers who want serious performance, better fuel economy, and the latest comfort and towing tech without sacrificing long-term reliability. The LML Duramax (2011–2016) delivered big gains in power and efficiency, putting down 397 hp and 765 lb-ft of torque while meeting stricter emissions standards. That's partly because of the diesel's efficiency advantage and partly because the 6.2-liter V-8 requires premium fuel, which, at the time of this writing, costs at least 40 cents more per gallon than diesel nationally. In addition to a higher compression ratio, the VVT turbo which produces significantly more torque at lower RPM’s, the LLY rods are more susceptible to bending at increased power levels. While the LLY made competitive performance numbers back in 2004, the engine is certainly not competitive to the modern day diesels. The tire is built to handle heavy loads and frequent use, making it ideal for commercial applications and work trucks. This tire is engineered to provide reliable performance and durability for work-oriented vehicles that spend most of their time on paved roads. The Firestone Transforce HT is a highway-terrain tire designed specifically for heavy-duty trucks and commercial vans, including vehicles like the 2500HD Duramax. This original 6.6L Duramax V8 turbo-diesel came to the market in a GM heavy duty pickup in 2001. It is superior to all others and offers the largest gain in horsepower and fuel efficiency. It can tune your truck to a whole new level, with the brand guaranteeing that you will gain up to 35 horsepower and an impressive 5mpg gain. It has been created with incredible passion by engineers who have made sure it will please you with its tuning capabilities, allowing you to gain more horsepower. 🔋 What Mileage Can You Expect from an LBZ? In addition to these two major benefits, performance monitors also offer a myriad of other benefits. Newer diesels have a lot more parameter monitoring built in to the display or cluster. Well, first they give you access to literally hundreds of parameters about your truck. If you have an aftermarket 4″ exhaust, make sure you also pickup two adapters with part # C11342. Well, for starters, a larger, free-flowing exhaust reduces exhaust gas temperatures (EGTS) and back pressure. Any factory exhaust, even the factory one of the LB7 still has much that can be improved. Therefore, the lack of these emissions work in the LB7’s favor. At the time, Duramax engines offered 520 pounds-feet of torque. Powerstroke engines can have issues like fuel injector failures and turbo problems. Power and performance are important for truck engines. It is not offensive and resembles the sound of an old Rochester Quadra-jet sucking air. It is my opinion that it was probably induced by a series of calibration protocols coming together, and possibly lower than desired cetane fuel. I did notice a higher degree of diesel clatter during one scenario. Brimming the tank after this drive showed an efficiency of 10.3 L/100 km, calculated based on the amount of fuel consumed and not the truck’s on-board computer. We filled up with diesel and took the same circuitous route in the same weather conditions, this time with the tonneau cover replaced by a lumpen John Deere. The diesel’s loping engine speed didn’t hurt, either. Topping off at the pumps after the drive revealed a fuel efficiency of 9.4 L/100 km, in with a shout of the official NRCan rating. The oil free Dry Flow air filter provides high air flow with great filtration and it’s washable and reusable so with the included Filter Minder Gauge, you know exactly when your air filter needs to be serviced. This kit was specifically developed for 2011 and 2012 GM 2500HD and 3500HD trucks with the 6.6L Duramax Turbo Diesel engine. The complete replacement airbox adds several cold air inlet ducts, while the oversize filter and replacement intake tube optimize airflow to the engine, and more air equals more power. Speaking with Airaid, they shared that “The MXP series is designed for high-performance diesel applications and we start with a new one piece roto-molded air box that addresses all the shortcomings of the restrictive factory design. This cool, dense air charge, is the key to getting more power from your engine.” Fortunately, the L5P doesn’t require many supporting mods as its fuel system can handle in excess of 750whp and the turbo is good for about 550whp. This will allow the turbo to spool more freely, improving its reliability and increasing power. A big 5″ exhaust system will add good sound, but a downpipe will actually provide better power gains and the most backpressure reduction. Despite putting this last on the list, it’s actually our favorite exhaust upgrade. Upgrading the intake horn to a 3.5″ diameter steel pipe will increase air flow and therefore increase power. Above all, you need tires perfectly compatible with the rim size for ultimate driving performance. It affects a vehicle’s fuel economy, noise level, and comfort. Its grip came into play just in time to balance my driving movements. On rough surfaces, this tire has an equally lively performance. After testing in the mud, I am delighted with the product’s performance. There have been several complaints about the turbocharger failing during cold or freezing temperatures, and most of these failures were due to bent fins. Although the turbocharger’s setup is simple and gets the job done, the system has experienced catastrophic failures. The turbocharger has vanes actuated by a rod controlled by an external control module. In the worst case, it will throw some error codes and drop your engine into limp mode until the issue is rectified. The pump usually goes bad during winter and is always on national backorder. Yet, it’s also not a big deal if you consider its persistent processing performance. As a longtime reviewer, I have never encountered any tire with snow performance as good as the Michelin Agilis Crossclimate. The major problems with this engine were issues with the emission system and turbocharger. Most problems identified, including carbon buildup, clogged injectors, and timing belt replacement, were either an issue peculiar to direct-injection engines or required routine maintenance. It’s always a little awkward discussing value on $80,000-plus trucks, but it’s a must. A 6.6-liter gas V8 making 401 horsepower and 464 lb-ft of torque is standard on Silverado 2500 and 3500 models. This further illustrates how Banks wins over other intake brands who simply design air boxes and exhaust systems with little or no engineering, selling parts that add nothing more than aesthetics. As standard, the Silverado 2500 HD gets a 6.6-liter V8 gas engine paired with a 10-speed automatic transmission.
