Procharger: High Output Intercooled Tuner Kit with P-1SC-1 for 2019-21 GM Trucks, 5.3L

Bolt on 40-45%+ more power to your Silverado or Sierra 1500!

If you have a 2020-2019 Chevy or GMC truck and, like most of us, would love to transform your new truck into an entirely different performance rig that truly does it all.  Well thanks to an easy to install supercharger system, you can enjoy loads more horsepower and torque for virtually anything you do with your truck.  Imagine having 50% more power to tow, 50% more power when you push the pedal to pass, or maybe just 50% more power to play when you are off road.  

ProCharger technology delivers industry-leading power gains thanks to the combination of our highly effective air-to-air intercooling and the efficient P-1SC-1 ProCharger.  These items combined with optimal mounting locations to avoid heat soak, ProCharger Systems and Kits are designed to give you that much needed boost in performance. The High Output (HO) Intercooled System is designed with durability in mind and provides 7-8 psi of engine friendly boost, for years of trouble-free use. The dedicated belt drive provides maximum power transfer from the engine to the supercharger, giving you increased efficiency and durability.

Tuner Kits: These kits make sense for someone wanting to perform custom tuning of the car and push the envelope in performance.  Will most likely be experimenting with alternative fuels such as 93 octane, race fuel, E85 fuel, and methanol supplemental fuel.  In addition, possibly changing engine components like heads, headers, exhaust, and cams for the engine.
