Description
Power and Performance. Improve the power and performance of your 2018-2023 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 Mustang is bone stock or if you have added a cold air intake, throttle body, exhaust or other bolt-on performance upgrades or running a Boss 302, Cobra Jet or GT350 intake manifold, 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 or E85 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 the following tuning devices (not included):
- HP Tuners MPVI2+ Tuner
- HP Tuners RTD "Remote Tuning Device" Tuner
- HP Tuners nGauge Tuner - unlocked
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 2018-2023 Mustang models equipped with the naturally aspirated 5.0L V8 engine. HP RTD Tuner required - not included. Aftermarket camshafts, aftermarket and/or ported Heads are not supported with this tune.
