REFUND POLICY

Last updated: [date]

Custom tuning and calibration files

All tuning products, calibration files, tune revisions, and tuning support packages are custom-built for your specific vehicle using the VIN, modification list, and goals you provide at checkout. Because each calibration is created for one vehicle and cannot be resold or reused, all tuning sales are final. No refunds, exchanges, or chargebacks will be issued for tuning products under any circumstances, including but not limited to:

  • Changing your mind after purchase
  • Selling or trading the vehicle
  • Mechanical, electrical, or fuel-system problems that exist on the vehicle before or after tuning
  • Inaccurate or incomplete information provided at checkout (wrong VIN, unlisted modifications, wrong transmission type)
  • Failure to install, download, or use the file
  • Loss or replacement of the flash device

If a calibration file does not load or the vehicle exhibits a drivability issue that is directly caused by the calibration, we will work with you to correct the file at no charge within [90 days] of purchase. Diagnosis of mechanical issues is not covered; we may require datalogs, photos, or a shop diagnosis before revising a file.

By completing a tuning purchase you confirm that you have read this policy and agree that the sale is final.

Flash devices, cables, and electronics

Unopened devices and cables in original packaging may be returned within [14 days] of delivery for a refund minus a [15%] restocking fee. Return shipping is the customer's responsibility.

Devices that have been opened, activated, registered, licensed, or "married" to a vehicle VIN cannot be returned or refunded; once a device is linked to a VIN it cannot be resold. Defective devices are handled under the manufacturer's warranty; we will help you start that process.

Parts and hardware

New, uninstalled parts in original packaging may be returned within [30 days] of delivery for a refund minus a [15%] restocking fee. Installed, modified, or damaged parts cannot be returned. Special-order and drop-shipped items are non-returnable. Return shipping is the customer's responsibility unless we shipped the wrong item.

Merchandise (apparel, stickers, accessories)

Unworn, unwashed merchandise with tags may be returned or exchanged within [30 days] of delivery. Stickers and clearance items are final sale. Return shipping is the customer's responsibility unless the item arrived damaged or incorrect.

Damaged or incorrect orders

Contact us within [5 days] of delivery with your order number and photos. We will replace the item or issue a refund.

How to start a return

Email [support@tsmcalibrations.com] with your order number before shipping anything back. Unauthorized returns will be refused. Approved refunds are issued to the original payment method within [5–10 business days] of receiving the item.

Chargebacks

Filing a chargeback on a tuning purchase after receiving the calibration file is a breach of these terms. We reserve the right to revoke tuning support and pursue the amount owed.
