Chevy Silverado / GMC Sierra 2019-2022 5.3L / 6.2L - DiabloSport Predator 2 Unlock & Tune Kit

The 2019-2022 GM gas trucks have been locked down since their introduction. Owners of these trucks have been waiting patiently for an affordable tuning solution, and DiabloSport has delivered in a big way! The new 9226-R kit includes our Predator 2 handheld tuner, along with the locksmith device and harnesses required to unlock both the ECM and TCM in your truck. Once unlocked, the Predator 2 offers up multiple tunes for the engine and transmission to choose from.

Beyond the preloaded tunes, we offer a host of user adjustable parameters, like throttle response, speed limit, tire size, and of course, DFM disable! We've even added some new features for drivers of these newer trucks, like the ability to recall your last mode setting, or to retain your auto-start-stop setting.
Get power you can feel, with DiabloSport!
