TUNED TO SEND IT
Purpose-built performance tuning for the off-road/competition Duramax 2017-2023. This is custom calibration dialed to your setup — crisper throttle, stronger power delivery, and the drivability that makes a built truck actually fun to drive on the track. Elite-level custom tuning with 4-week support, delivered as a custom tune file. Requires a compatible EZ Lynk AutoAgent device (sold separately).
