A color touchscreen tuner that plugs into the OBD-II port, loads one of four preloaded tunes, and then stays mounted as a gauge and diagnostics display. This version includes the locksmith unlock service the 2019-2022 GM computers require before they will accept a tune.
why this one — Buy the CTS3 if you want the monitoring as much as the tune, since it reads live engine data and trouble codes on the same screen you tuned with. On price it sits between DiabloSport's two kits. Edge publishes no horsepower figure for it, and the listing rules out 2022.5 refresh trucks and any E-Assist or hybrid setup.
Not available to ship to California per the listing (CARB pending).
