Refund & Returns Policy

Our policy covers two categories of products:

• Digital items such as tuning files and software.
• Physical items such as diagnostic tools, cables, and accessories.

Different terms apply to each due to the nature of these products.

Once a digital product (such as a tuning file, calibration, or software activation) has been delivered, it cannot be refunded or exchanged.

This is because:

• Digital files cannot be “returned” once downloaded or accessed.
• Every tuning file is custom-developed for the customer's vehicle or request.

However, we stand by the quality of our work and offer technical support and file revisions to ensure your satisfaction.

If you experience issues with a tuning file, please contact our support team at info@dttuning.com — we'll work with you to resolve it promptly.

If you purchase a physical item from our store (e.g. Magic Motorsport, Alientech, Autotuner, or related accessories), the following terms apply:

Damaged or Faulty Items

If an item arrives damaged, defective, or not as described:

• Contact us within 14 days of delivery.
• Provide your order number, photos of the issue, and a brief description.
• We will review the case and arrange a replacement or refund if eligible.

Returns (Change of Mind)

If you change your mind or order the wrong item:

• You may return it within 14 days of receipt, provided it is unused and in its original packaging.
• The customer is responsible for return shipping costs.
• Refunds will be processed once the item is received and inspected.

Non-Returnable Items

We cannot accept returns for:

• Used, installed, or activated electronic devices
• Items damaged due to misuse or incorrect installation
• Software activation codes, licences, or digital keys

Once your return is approved:

1. You'll receive confirmation via email.
2. Refunds will be issued to your original payment method within 5–10 business days, depending on your bank or payment provider.
3. If a replacement is chosen instead, tracking details will be provided once dispatched.

• Shipping costs are non-refundable, unless the item was faulty or sent in error.
• If returning a high-value item, we recommend using a tracked or insured courier service.

If you have any questions or need to start a return, please contact us:
