POWER UP YOUR 2017 - 2019 DURAMAX WITH PROVEN UPGRADES

The 2017 Duramax model year marked a significant leap forward in GM’s diesel lineup. Released in 2017, this engine came out strong with 445 horsepower, establishing itself as a class leader. Despite rumors of a potential displacement increase, GM stuck with the 6.6L configuration, focusing instead on overhauling key engine components and boosting overall durability.

The 2017 - 2019 Duramax engine received a number of critical upgrades, from a stronger block and crankshaft to reinforced rods and remelted pistons. The fuel system was redesigned for more efficient delivery, while the camshaft profile was adjusted for optimized performance. Even the transmission saw improvements, with the revised Allison 1000 transmission built to handle the additional power.

Not to mention, the hood scoop on the 2017 - 2019 Chevy Duramax and 2017 - 2019 GMC Duramax is fully functional, increasing airflow by 60% and ensuring the engine runs cooler even under heavy loads. With these factory upgrades, the L5P Duramax is primed for additional aftermarket enhancements that can take your truck to the next level.

Q: What are the most common issues with the 2017 - 2019 Duramax engine?
A: The 2017 - 2019 Duramax engine, while highly reliable, has a few common issues reported by owners. Some of these include turbocharger boost leaks, which can reduce performance, and injector wear over time, leading to decreased fuel efficiency. Another critical failure is that of the CP4 injection pump. The CP4, while designed to run at exceptionally high RPM’s, is a cause for concern as when it fails, it typically sends shrapnel throughout the fuel system causing the necessity of replacing the injectors, fuel rails, fuel lines, and flushing the tank. Additionally, there have been reports of issues with the Allison transmission when towing heavy loads. Regular maintenance of critical components like the turbo and injectors can help prevent these issues and keep your 2017 - 2019 Chevy Duramax running at peak performance.

Q: How can I improve the performance of my 2017 - 2019 GMC Duramax for towing?
A: Improving the towing performance of your 2017 - 2019 GMC Duramax can be achieved by upgrading key components. A turbo upgrade will increase power and provide better throttle response, while high-performance injectors will improve fuel delivery. A cold air intake and high-flow DPF back exhaust system can also help your engine run cooler and more efficiently, especially when hauling heavy loads. A performance chip will allow you to fine-tune your settings for the best street and towing performance possible.

Q: Are parts for the 2017 - 2019 Chevy / GMC 6.6L L5P Duramax still available?
A: Yes, parts for the 2017 - 2019 Chevy / GMC 6.6L L5P Duramax are widely available. Diesel Power Products offers a comprehensive selection of performance parts, including injectors, turbo kits, exhaust systems, and more, to keep your 2017 - 2019 Duramax running smoothly. Whether you're upgrading for performance or maintaining factory standards, we have the parts you need to keep your truck performing at its best.

Q: What upgrades should I consider for my 2017 - 2019 Chevy Duramax?
If you're looking to get more out of your 2017 - 2019 Chevy Duramax, consider upgrading to high-performance injectors, a larger turbo, and a high-flow exhaust system. These parts will increase power and efficiency while helping the engine run cooler. Additionally, installing a cold air intake will improve airflow and fuel economy. Performance chips are another great upgrade, allowing you to fine-tune your 2017 - 2019 L5P Duramax for different driving conditions.

Q: I have an EFILive AutoCal for my earlier Duramax. Can that same tuner work on my L5P Duramax?
A: In short, no, EFILive has not yet updated their files to allow L5P tuning to be loaded into their AutoCal tuning devices.

Q: Will a DPF (Diesel Particulate Filter) back system provide more sound to my truck?
A: Generally speaking no, the emissions equipment upstream will still act as a muffler. However, that doesn't mean installation will not help in other areas by improving exhaust flow. While minor, the benefits are noticeable, plus an aftermarket exhaust looks way better than the stock exhaust.

Q: I'm looking at an exhaust kit on your website, but it doesn't state which cab and bed configuration it fits, will this fit my application?
A: In most cases, unless it is specifically stated as fitting a certain configuration, all exhaust kits on our website will fit all cab and bed lengths. Further, most kits will not fit cab and chassis applications unless otherwise noted.

Q: I'm looking at this 5" (or other) exhaust kit, but my truck only has a 4" exhaust now. Does this 5" exhaust include an adapter / reducer?
A: Yes, the exhaust systems we sell will adapt down to fit the application at the designated starting point (turbo back, cat back, DPF back, etc.) for a hassle free installation.

Q: What are EGT's?
A: EGT stands for Exhaust Gas Temperature, which is the temperature of the exhaust leaving your engine. This measurement is typically measured before the turbo to ensure you are not overheating components. For most applications, we recommend not exceeding 1300 degrees.

Q: Will the products you offer void my warranty?
A: Some parts may void your warranty and some may not. We recommend researching the Magnuson-Moss Warranty Act that specifically protects consumers when choosing to install aftermarket components on their vehicles, as well as consulting with your local dealer.
