2020 Chevy 6.6 Overview

The 2020 Chevrolet Silverado 2500HD and 3500HD are the company’s most sophisticated pickup trucks. They come in a variety of models, offer a plethora of features, and can practically move mountains. Chevrolet also offers two powerful 6.6-liter V-8 engines: one with 464 lb-ft of torque and another with 910 lb-FT of torque from the Duramax engine. The latter allows the Silverado HD to tow up to 35,500 pounds, making towing chores easier than ever before. Naturally, when the day is done and it’s time to unwind, more expensive versions offer a wider range of facilities. The GMC Sierra HD and the Silverado versus the Ford Super Duty and Ram 2500 and 3500 are a battle between supersized models. While neither GM vehicle is the best heavy-duty pickup in its class, Bow Tie fans will be satisfied with its distinctive appearance and big features.

General Motors produces the Duramax family of 6.6L engines in the United States and DMAX, a GMC-Isuzu collaboration that engineers and manufactures engines, is located in Ohio.

  • With 22 percent more torque and up to 18% more towing, the new 6.6L V-8 gas engine with direct injection is more powerful and stronger trailering capability than the previous 6.0L gasoline engine.
  • The transfer case on 4×4 vehicles is an Autotrac two-speed automated transfer with active control that electronically manages “4 Auto” mode, allowing the truck to shift between two-wheel drive and four-wheel drive based on road conditions.
  • The Adventurer 300 boasts a new transparent trailer view, as well as Advanced Trailering System technologies and other fresh ideas: The in-vehicle towing system has 15 different camera views available, such as HD Surround Vision3 and various unique perspectives.
  • The most distinctive aspect about the Silverado 1500HD’s body is its unique exterior design, which includes the most variation from the previous generation of Silverados — there’s just one sheet metal roof.
  • Heavy-duty features such as an easier-access engine block heater cord outlet in the front bumper, a more integrated snow plow prep package, and new, optional trailing mirrors with perimeter and auxiliary lighting that make work simpler and more intuitive.
  • The rear hatch is larger than the previous model, which includes a CarryOn version. A new stowaway feature, called BackPackProfiles, allows for easier loading and retrieval of items in the cargo bed, designed to carry up to 500 pounds.
  • The extra space allowed by a larger cab makes it easier to transport large items or people in your pickup. Crew Cab models add roughly 3 inches in overall length, allowing for additional spacious interiors.

If you don’t have any experience with cars, dealing with anything automotive-related may be difficult. The finest tuners will be simple and user-friendly for the general public to install without being overly complex to use or modify if necessary.

How To Get The Most Out Of Your L5P

The L5P Duramax without any help from the aftermarket produces impressive results. That does not imply, however, that your L5P Duramax may not be improved. There are several aftermarket modifications that can improve horsepower, torque, fuel efficiency, or durability without breaking the bank for everyone. Our list of the 5 best L5P Duramax Performance Improvements has something for everyone whether you want a little more get-up when passing others or making your truck bulletproof.


6.6L L5P Duramax Tuners

An inexpensive, emissions-compliant tuner is one of the most effective L5P Duramax performance modifications. They boost horsepower and torque significantly, as well as improve throttle response. Five of our favorite L5P Duramax tuning products are listed below. Installing an L5P Duramax may be a bit more difficult than installing a tune because it’s more advanced.

Cracking the L5P Duramax is no more difficult than hacking into a NASA computer. The Banks Derringer, Edge Pulsar, and AFE scorcher are fantastic alternatives if you want modest gains without dealing with your ECM. If you want genuine bespoke L5P Duramax tuning, you’ll have to buy an ECM swap, HP tuning hardware, and custom tunes separately. Right now, PPEI and DuramaxTuner provide HP tunes for the L5P.


L5P Duramax Cold Air Intakes

The addition of a cold air intake to an L5P Duramax is a simple and inexpensive performance boost that improves horsepower and torque. While intakes aren’t as poorly designed as the OEM ones used on trucks 10 years ago, they are still restricted. An upgraded cold air intake increases airflow, which helps you get better mileage and performance. Some cold air intakes even claim to lower the amount of regenerations that take place. Because many of the aftermarket parts don’t demand frequent maintenance or have a washable filter that can be removed, cleaned, and replaced, maintenance may be simpler.

L5P Duramax Exhaust Kits

Unfortunately, because the L5P Duramax doesn’t have an emissions-deleting tune port, a turbo-back exhaust system can’t be used. If you live in the United States and register your truck with the DMV, it’s against the law to remove its emissions. While some states don’t require emissions tuning, maintaining them is still encouraged. When exhaust systems are turbo-back or down-pipe-back, they provide the most significant improvements. They are DPF-back exhausts, as evident by the L5P Duramax exhausts listed below. Air flow is somewhat more powerful, the sound is somewhat better, and back pressure has been reduced. However, compared to stock Duramax exhausts, they do appear to be significantly better. 2020 Chevy 6.6 Performance.

Aftermarket Fuel Tanks

The last L5P Duramax Performance upgrade is often neglected. While an aftermarket fuel tank won’t make you any more horsepower, it will enable you to go further and be picky about your source. We only purchase from well-maintained, busy gas stations. We’ve previously had fuel pump issues caused by poor diesel, so we’re doing everything possible to avoid that from happening again. When you’re on the road, going camping, or just driving around town, aftermarket fuel tanks are fantastic. The majority of trucks come with a 36-gallon stock L5P Duramax tank. A 56-gallon tank will extend your range by 200-300 miles, and they’re designed to fit in the same space as your OEM tank. They’re also re-calibrated by GM dealerships to match your truck’s larger petrol gauge, 2020 Chevy 6.6 Performance.


If you want to take your truck’s performance to the next level, you should invest in a high-quality tuner. Consider what features you want in your tuner, and go with one of our top picks – we promise you will not be disappointed! And we guarantee that your truck and engine will thank you as well.
