TUNED TO SEND IT
Custom performance tuning for your Cummins , built for off-road and closed-course competition. Your tuner calibrates the ECM to your exact build and goals — waking up throttle response, sharpening power delivery, and pulling stronger through the RPM range. Includes Switch-On-The-Fly so you can move between calibrations on the fly. Elite-level custom tuning, for the MM3 platform. Requires a compatible MM3 device (sold separately).
