The 2019-2022 (22.5+ refresh not supported at this time) GM gas trucks have been locked down since their introduction. Owners of these trucks have been waiting patiently for a tuning solution, and DiabloSport has delivered in a big way! The new 8225-R kit includes our industry leading inTune 3 handheld tuner, along with the locksmith device and harnesses required to unlock both the ECM and TCM in your truck. Once unlocked, the inTune 3 offers up tunes for 87, 91 and 93 octane fuels, as well as 2 transmission tunes to choose from, in addition to supporting custom tunes from our network of GM CMR tuners. 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!
