Refund & Returns Policy
Last Revised: December 17, 2025
At Diamond Tuning & Performance, we aim to provide high-quality services, accurate diagnostics, and reliable merchandise. We understand that situations may arise where you have concerns about a purchase or appointment, so this policy explains how refunds, cancellations, and returns are handled.
1. Service Refunds (Tuning, Diagnostics, ECU Flashing, Custom Work)
Because our tuning and diagnostic services involve time, labor, and customized adjustments specific to your vehicle, all service sales are final.
However, we stand behind our work. If you believe something is not performing as expected, please contact us within 7 days of your appointment. We will:
Review your concern
Recheck the tune or diagnostic results
Make reasonable revisions when necessary
Refunds are not provided for services already performed, but we will work with you to ensure the best possible outcome.
2. Dyno Tuning (When Available)
Dyno runs, tuning sessions, and related labor are non-refundable once the session has begun.
If you need to reschedule, please notify us at least 24 hours in advance.
Same-day cancellations or no-shows may result in a cancellation fee.
3. Merchandise (Shirts, Hoodies, Keychains, Etc.)
Returns & Refunds
We accept returns on unused, unworn merchandise within 14 days of delivery.
Items must be:
In original condition
Unwashed
Free of odors, stains, or wear
In original packaging (if applicable)
You are responsible for return shipping costs unless the item arrived damaged or incorrect.
Exchanges
If you need a different size or received a defective product, we are happy to process an exchange. Please contact us within 7 days of receiving your item.
4. Digital or Downloadable Products (If Offered in the Future)
Any digital files, such as tuning forms, downloadable documentation, or digital merch—are non-refundable.
If a file is corrupted or inaccessible, we will resend or replace it.
