Please follow steps to receive a tune revision:
1. Purchase the Mustang Tune Revision and complete the order
2. Fill out the tuning form after the order is complete with the new list of mods. (For vehicle strategy just enter in NA. We should already have it on file)
Additional Ordering Information – Under normal circumstances custom tunes are delivered via email within two business days of completing the custom tuning sheet.
The custom tuning sheet link is downloadable after you complete your purchase. This is how we collect the vehicle and tuner data necessary to write your custom tunes. To eliminate delays please whitelist @gearheadautomotiveperformance.com email addresses in your email client so your spam filter does not block delivery of emails from us.
3. Keep an eye on your email for the tune files. (Typical turn around for revisions are 2-3 business days.)
