  • Hi I currently bought an 04 duramax with this tuner installed and wasnt told which numbers do what would yall be able to tell me?

    Garrett Rorison | 8/3/2020

    The tuning levels would vary depending on the tuner. Here is Duramax tuners levels.

    • Optimized Stock - Power delivery smoother than stock with near stock output -Refined timing tables for lower EGTs and higher efficiency
    • Heavy Tow Tune - 60rwhp over stock- Refined timing tables for lower EGTs- Throttle pedal revised for simplified low speed trailer maneuvering- Built for towing loads from 8000lbs to gross vehicle weight
    • Light Tow Tune - 80rwhp over stock -Refined timing tables for lower EGTs -Throttle pedal revised for simplified low speed trailer maneuvering -Built for towing loads under 8000lbs
    • Sport Econ - 100rwhp over stock -Best balance of power reliability and efficiency for unloaded daily driving -Low smoke output -Throttle sensitivity increased for less throttle input, quicker shifting and less average RPM in daily driving situations
    • Stock Trans Race Tune - 130rwhp over stock Maximum horsepower tune for stock transmission- If abused, has the potential to shorten the life of your stock transmission Typically will run mid 14's near 93 MPH on a truck setup for drag racing

  • Do you need a tuner also to use this switch?

    Jeff | 5/16/2020

    yes, this switch works in conjunction with EFI tuning.
