Edge Evolution CTS3 Tuner and Monitor for 1999-2016 GM Gas Trucks SUVs and Cars 4.8L 5.3L 6.0L 6.2L - 85450-250

The Edge Evolution CTS3 85450-250 is a plug-in tuner and 5 inch touchscreen gauge monitor for 1999-2016 GM gas trucks, SUVs and cars with the 4.8L, 5.3L, 6.0L and 6.2L V8s and several other engines. It flashes preloaded tunes through the OBD-II port for daily driving, towing, economy and performance, then stays on the dash as a live gauge display.

The feature most owners buy it for is Active Fuel Management (DOD/AFM) disable, which keeps the engine in V8 mode full time. Tire size and gear ratio correction, speed limiter adjustment and code reading come with it.
