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. Includes Switch-On-The-Fly so you can move between calibrations on the fly. Elite-level custom tuning, for the EFI Live platform. Requires a compatible EFI Live device (sold separately).
