    Power and Performance. Improve the power and performance of your 2020-2022 Shelby GT500 Mustang with a Lund Racing Custom Tune File. When your Mustang rolled off the assembly line, Ford programmed it to cater to the needs of the daily driver, not the performance enthusiast who adds aftermarket bolt-on modifications in the search for more power. So, if your Shelby Mustang is bone stock or if you have added a cold air intake, throttle body, exhaust or other bolt-on performance upgrades, you'll need a Lund Racing custom tune to see the full power potential that these aftermarket mods can make.

    One Custom Lund Racing Tune File. This dyno-tested custom tune file that is written specifically for your Mustang and your particular modifications by a Lund Racing calibrator. By optimizing the air/fuel ratio, adjusting ignition timing and tweaking cam timing, a Lund Racing Custom Tune will squeeze out the extra power Ford left on the table. This tune requires the use of 91-93 octane fuel.

    Free Tune Revisions. Lund Racing will provide tuning revisions for minor modifications free of charge for up to 6 months after you’ve received your initial tune. Changes to your air intake, throttle body, exhaust, gears are all considered minor modifications. The countdown starts from the time you receive the tune(s) which may be up to 7-10 business days following your order.

    Device Compatibility. This Lund Racing Custom Tune File is only compatible with HP Tuners RTD tuning devices - not included. This Tune is not compatible with any other tuning devices.

    Will Not Ship To California. Due to state regulations, this product cannot be shipped to addresses in the state of California. Lund Racing will not write or provide custom tune files for residents of California.

    Application. This Lund Racing Custom Tune File is specifically designed for 2020-2022 Shelby GT500 Mustang models equipped with the supercharged 5.2L V8 engine that are running pump gas with basic bolt-on modifications.
