Diablosport Trinity 2 Tuner with ECM and TCM Unlock (19-21 V8 Sierra 1500; 2022 V8 Sierra 1500 Limited)Find parts that fit my vehicle

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 9225-R kit includes our industry leading Trinity 2 on-dash tuner, along with the locksmith device and harnesses required to unlock both the ECM and TCM in your truck. Once unlocked, the Trinity 2 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 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.
Of course it doesn't stop there with T2. The full color, 5" touch screen allows you to keep an eye on all your vital engine data. The on-screen gauges deliver all the info you want to see, in real time. Of course, it can also record data for playback on our DV2 software for further analyzation. T2 also allows you to set up virtual alerts, and supports our Expandable Accessory System (EAS) for adding and logging additional external sensors. The device is internet updateable, either through our Update Agent software, or through its built in WiFi.
