TUNED TO SEND IT
Custom performance tuning for your Duramax 2017-2023, 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. Elite-level custom tuning with lifetime support, delivered as a custom tune file. Requires a compatible EZ Lynk AutoAgent device (sold separately).
