Edge Evolution CTS3 Tuner and Monitor for 2017-2020 Silverado Sierra Tahoe Suburban Yukon Corvette 5.3L 6.0L 6.2L - 50 State Legal - 85452-252

The Edge Evolution CTS3 85452-252 is a plug-in tuner and 5 inch touchscreen gauge monitor for 2017-2020 GM gas trucks, SUVs and the Corvette with the 5.3L, 6.0L and 6.2L (and 4.3L) engines. It carries CARB Executive Order D-802-10, so it is legal in all 50 states. It flashes emissions-compliant tunes through the OBD-II port and then serves as a live gauge display.

Included: AFM/DOD disable for full-time V8 operation, tire size and gear ratio correction, speed limiter adjustment and power levels for daily driving, towing, performance and economy. For the 2017-2019 full-size 1500 trucks it fits the legacy body style only; the 2019 and newer new-body 1500 has a locked ECM and needs an unlock kit such as the DiabloSport Trinity 2 9225-R.
