Which Tune File do I Choose?

    October 31st, 2018

    Gasoline Engine: Tunes are based on Octane, make sure you choose the correct octane rating based on the octane you are running in your vehicle.

    87 Octane
    91 Octane
    93 Octane


    Diesel Engines: We offer a few tunes based on what you’re going to be doing with your truck.

    Performance: The most aggressive preloaded diesel tune. Good for everyday use, racing, or economy but not recommended for any type of towing.
    Street: Less power than Performance. Moderate gain over stock, safe for light towing, under 5k lbs.
    Tow: Should be used when towing any significant load. Shifting is towing centered
