Lund Racing Custom Tunes are created specific to your EcoBoost powered S550 based on your exact modifications. This makes their tuning much more than just a typical "canned" tune. Lund Racing has been setting the standard in Ford Mustang tuning for many years in the past, and for many years to come. Make sure your tune is a Lund Tune.

Tuning revisions for minor modifications are free of charge up to three months after you??ve received your initial tune. The countdown starts from the time you receive the tune(s) which may be up to 7-10 business days following your order. Following that period, cost to renew for an additional three months of revisions is $50.

Changes to your air intake, throttle body, exhaust, gears, etc. are all considered minor modifications. If you need a tune revision, please click the link to the support page on Lund's website. ( You must sign up, and submit a request with your original order number from Steeda from when you purchased the original tune. You are going to need to provide Lund the PCM Code, Flasher Serial Number, and full modification list. Lastly, they will need you to let them know what you have changed on the car so that they can make the correct tuning revisions for your modifications.

Tuning revisions for major modifications will require a remote tuning session. The remote session will carry a fee of $400 if you have already purchased a tune directly from Lund Racing or Steeda. Additional remote sessions within three months of the original remote session purchase carry a fee of $200. Outside of three months of the original purchase, remote sessions will cost $400. Remote session customers who require a revision for minor modifications may buy back into a three month revision period for the standard $50 rate.

Below is a list of some of the major modifications that usually require a remote tuning session. Ultimately, depending on what you change on the car, Lund will decide at their discretion if the modifications will require a full remote tuning session or not. They handle this on a case by case basis.

Switching fuels (Ex. 93 octane to E30)

Changing Turbo

Adding Nitrous

Internal engine work (Heads, cam, etc.)

Changing injectors
