Evolution vs. The Competition

In the crowded L5P tuning market, the Edge Evolution CTS3 stands out with real results, not hype.

The results spoke for themselves: the Evolution delivered up to +88 HP and +215 lb-ft more torque at 2,100 RPM, and +98 HP and +244 lb-ft over stock, while maintaining lower EGTs and cleaner emissions output. The CTS3 offers seamless in-cab ECM and TCM unlocking, 10-speed transmission tuning, and easy calibration control, all through a single touchscreen device. With fast installation, powerful results, and proven reliability, the Evolution CTS3 unlocks the full potential of your L5P Duramax without the complexity or added cost of external software or hardware.
