    Power and Performance. Improve the power and performance of your 2015-2017 GT 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 fuel or E85.

    Free Tune Revisions. Lund Racing will provide tuning revisions for minor modifications free of charge for up to 3 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 compatible with the nGauge tuning device and SCT tuning devices (not included).

    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 2015-2017 GT Mustang models equipped with the naturally aspirated 5.0L V8 engine. Aftermarket camshafts, aftermarket and/or ported Heads are not supported with this tune.

    Application Notes. For Mustangs running pump gas with basic bolt-on modifications, see part# 406267. For Mustangs running E85 with basic bolt-on modifications, see part# 406268. For Mustangs running pump gas and an aftermarket intake manifold, see part# 406269. For Mustangs running E85 and an aftermarket intake manifold, see part# 406270.

    **Please Note: The custom tune files will be emailed directly to the end user within 4 business days from Lund Racing. Submit your Mustang's Info Here

      I installed a 2018 Mustang GT manifold on my 2017 Mustangt GT so I needed this tune. Lund had the tune back to me in two days and it was super easy to upload. I can pull up to 7800 and don't feel any of a power loss. The only hard part was on install when some of the bolts were dirty and hard to get off. Other than that super easy.

      Got a tune for my 16 gt, needed one for my PMAS CAI works great, notice a difference in the power of the car. And it was a quick turn around time from Lund. Worth the money.

      Feel the power!!!

      What can I say that hasn't already been said about Lund Tunes before: they're great! Prior to Lund, I always stuck with Bama. After constantly losing to a friend's Lund tuned car, I decided to give it a try. All I can say is that Lund has made yet another believer out of me! I haven't had the car dynoed, but my butt dyno definitely tells me that there is a noticeable gain, even compared to the bama tune. From everything I've read, Lund's tunes are reliable and safe, so I hope this is true. Until then, I will continue to enjoy the shocked faces of fellow 5.0 owners as my car most certainly leaves them wishing that they had a Lund race tune of their own!

    Will this work with an Edelbrock 2650 stage 1 SC? If not can you give me link for the Lund tune that will? Thanks

    • Lund can indeed tune for a supercharger, however this specific tune offer is for Stock/Basic Bolt-on Modifications or Aftermarket Intake Manifold applications.
