There is no denying how well GM has executed these latest generation heavy-duty trucks. The 2020+ Silverado and Sierra has been a total success in the market and that L5P Duramax paired with the all-new 10-speed Allison transmission is just flat out impressive. While this truck was a real showstopper in the show room outfitted with the top of the line Denali package with its massive chrome grille, factory 20” wheels, and enough cameras to see virtually everything in a 360-degree radius around the truck, of course it couldn’t be left stock for long.
In the first part of this project, we added a nice rollup Lorado tonneau cover from AgriCover, a DPF-back exhaust system from MBRP and a high flow intake tube and turbo inlet pipe from Wehrli Fabrication. We followed up those modifications with a 2” leveling kit from ReadyLift, 34” Toyo Open Country A/T’s and some unique gloss black milled 20” Rogue wheels from our Anthem Off-Road. With the truck finally looking the part, it’s time to get back under the hood for some added performance. You may think that Duramax packs enough punch to do everything you need it to, while we can somewhat agree, it’s hard to not mention that laggy pedal feeling GM programmed into the truck. Besides, if you knew how simple it was to add another 130+ horsepower with power adjustability on the fly, we know you’d ask us how. So, we’ll just tell you and save everyone the time of having to talk about.
