Refund Policy


Software and tuning are intangible goods.  Customer shall not ever be entitled to any refund rebate, compensation, or restitution for any reason whatsoever, even if the software contains material flaws.

Other items:

Customer shall exercise reasonable and timely diligence in discovering and reporting to T&B DIESEL TUNNING any damage or shortage in materials and parts. Please be aware that original shipping packaging is not weatherproof. Thus, immediate, proper storage of packages upon and after delivery is required.  Claims for missing parts, damage in shipping, defective merchandise and/or requested returns must be submitted via telephone or a support ticket created at (“Contact Us”) within 30 days after documented delivery date of receipt of ordered items to Customer.   A company representative will then provide a pre-paid return label.   All non-defective and unused returns are subject to a 10% restocking fee. Customer shall have 15 days from emailed receipt of return label to tender the item to the courier. Absolutely no return or refund will be allowed after 60 days from order date.

Unless T&B DIESEL TUNNING determines the product to be defective, upon receipt of the returned item, a refund of the price of the item (less the 10% restocking fee) and any applicable taxes will be issued in the original form of payment used to purchase the item or via a check or electronic payment from T&B DIESEL TUNNING.  In order to qualify for a refund, all items must be completely unused, in the original packaging, and in the same condition in which the item was received.  The original shipping charge is not refunded when returning unused or non-defective items. If you received a discount or free item by purchasing multiple items together, you will lose that benefit if you do not return all items together.  We may suspend or cancel payment or refuse to honor a refund request if we find evidence of fraud, abuse, unlawful or other manipulative behavior.
