Description
Unlock your 2017–2019 GM L5P Duramax 6.6L diesel truck’s full potential with the Edge Evolution CTS3 85400-262, featuring built-in ECM unlock using the included Locksmith device and unlock cable. This all-in-one performance tuner gives you unmatched control, diagnostics, and tuning ability—all from the cab of your truck.
After years of success with the EvoHT2, Edge has now brought its revolutionary in-vehicle ECM unlocking technology to the CTS3 platform, enabling full ECM tuning and monitoring with a powerful, high-resolution 5" touchscreen display. With tuning options that boost up to 150 HP and 350 lb-ft of torque, you'll experience drastically better throttle response, turbo spool-up, and fuel economy.
This device can unlock and tune only one vehicle. Once the ECM is unlocked, the process is irreversible, and the device becomes VIN-locked.
Requires a PC with Edge’s Update Agent software to complete installation and flashing.
