Custom ECU calibration for Cummins, Duramax and Powerstroke platforms. We build tune files matched to your fuel system, hardware, and goals — whether that's daily driving, towing, or all-out performance.

Delivered as a custom tune file for your existing device, or performed live via remote flash. Most files are delivered within 24 hours.
