DiabloSport inTune 3 Unlock and Tune Kits 8266-R

Unlock and tune your truck in your driveway with DiabloSport inTune 3 kits.

GM gas trucks have been locked down since their introduction, but DiabloSport's inTune 3 unlock and tune kits provide tuning solutions that include the handheld tuner, along with their industry exclusive locksmith device and harnesses required to unlock the ECM in your truck. Once unlocked, the inTune 3 offers tunes for 87, 91, and 93 octane fuels, as well as two transmission tunes to choose from. Beyond the preloaded tunes, the kits offer a host of user adjustable parameters, like throttle response, speed limit, tire size, and more, and DiabloSport has also added some features for drivers of these newer GM trucks, like the ability to recall your last mode setting.
