The 2020-2023 6.6 L8T 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 8266-R kit includes our inTune 3 handheld tuner, along with our industry exclusive locksmith device and harnesses required to unlock the ECM 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. Beyond the preloaded tunes, we offer a host of user adjustable parameters, like throttle response, speed limit, tire size, and more.
