Recent General Motors products have been a nightmare when it comes to tuning and any bolt on engine mods. But that doesn’t stop some people from trying, for better or for worse. This attempt at a procharged 2019 Chevrolet Silverado, built by Late Model Racecraft, looks like it actually went well. It also happens to be the first ProCharged Silverado in the world, according to the tuning company.
The upgrades are just want you’d want in a boosted street tuck, other than the questionable amount of chrome on the exterior. LMR put on a Cam Motion cam, some new pistons, American Racing Headers, a Borla exhaust, and the all-important Procharger centrifugal supercharger.
All together, it pushed 636 hp and 635 lb-ft of torque to the wheels on a conservative tune in a dyno test. It also survived the dyno test without breaking, something that can’t be said for most boosted C8 Corvette attempts. In the video, LMR say calibrating the electronics was the most difficult part of the build, and it unsurprisingly took a long time to get everything running smoothly.
To our eyes and ears, the idle isn’t quite as smooth as a stock truck would be, and the transmission seems a little off. Plus, the traction control gets so bogged down in the video that the modded truck gets left behind the stock truck in a pull. In the second race, the traction control gets switched off, and the ProCharged truck destroys the stock one right off the bat. LMR also says they can work on those issues down the line, but want to hear the customer’s thoughts first.
It’s good to see the tuning community is finally getting their heads wrapped around GM’s tricky new ECM in the 2019 and newer Chevrolet Silverado and GMC Sierra. But unfortunately, more stringent software similar to the C8 Corvette will eventually make it’s way to GM trucks, and tuners will have even more difficulty getting any mods put on the trucks. If it were our choice, we’d forget the challenging mods and wait for the Silverado ZR2.
