DiabloSport Trinity 2 EX GM E90/T93 Unlock and Tune Kit (in-cabin touchscreen tuner)

An in-cabin touchscreen tuner sold together with the ECM and TCM unlock that a 2019-2022 GM 1500 needs before it will accept any aftermarket tune. It comes preloaded with 87, 91 and 93 octane tunes plus two transmission tunes, and the screen stays mounted afterward as a gauge display.

why this one — Pick this over DiabloSport's i3 handheld if you want the larger dash mounted screen and live gauges, since the unlock and the tunes themselves are the same for about $127 more. It also disables DFM so the engine runs on all eight cylinders full time. It does not fit 2022.5 refresh trucks, and DiabloSport publishes no power number for this kit.
