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 our website. (http://support.lundracing.com) You must sign up, and submit a request with your original order number from wherever you purchased the original tune. You are going to need to provide us the PCM Code, Flasher Serial Number, and full modification list. Lastly, we will need you to let us know what you have changed on the car so that we can make the correct tuning revisions for your modifications.
For customers changing to a different intake manifold, all aftermarket manifolds for 11-17 incur an additional $100 fee.
Tuning revisions for major modifications will require a remote tuning session. You can learn more about the remote tuning session here. The remote session will carry a fee of $400 if you have already purchased a tune directly from Lund Racing, or from one of our dealers. 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, we decide at our discretion if the modifications will require a full remote tuning session or not. We handle this on a case by case basis.
- Switching fuels (Ex. 93 octane to E85)
- Adding/changing Supercharger or Turbo
- Adding Nitrous
- Internal engine work (Heads, cam, etc.)
- Changing injectors
For individuals who have purchased a vehicle previously tuned by us: We will offer tuning support within our guidelines using the tuning device we wrote the original tune for. Please contact us before purchasing anything.
As always, please contact us before placing an order if you have any questions.
