Edge Evolution CTS3 Tuner (Part #85400-300)

Plug-and-play in-cab tuner and 5-inch color monitor for 2003–2012 Dodge/Ram 2500 and 3500 Cummins trucks. Covers 2003–2007 5.9L Cummins and 2007.5–2012 6.7L Cummins.

Unlock more pulling power, throttle response, and drivability without opening the hood. The Evolution CTS3 flashes engineered calibrations through the OBD-II port, saves your stock tune so you can return to factory at any time, and stays on the dash as a live multi-gauge display.
