Terms & Conditions

Pricing

All prices are in USD. The price shown is the final purchase price. All displayed tune prices are final as displayed. No sales tax is added to the displayed price or during checkout at this time.

Tune Delivery

Custom calibrations are typically ready within 24–48 business hours after TWZ has everything required to begin calibration. This is an estimated processing period, not a guaranteed delivery time. EZ LYNK profiles are shared through the AutoAgent app after the vehicle is successfully Lynked to TWZ. File-based tune/calibration files are delivered electronically by email or another method specified by TWZ.

EZ LYNK Tune Delivery

Your custom tune(s) will typically be available within 24–48 business hours after your vehicle has been successfully Lynked to TWZ Tuning and we have received all required vehicle information. Once completed, your tune profiles will be shared directly to your EZ LYNK AutoAgent account and will appear in the AutoAgent app under Vehicle → ECU Profiles.

The 24–48 business-hour processing period begins after your vehicle is successfully Lynked to TWZ Tuning and all information required to build your calibration has been received.

Email provides order confirmation, instructions, technician-link information and status notifications. Actual ECU profiles are shared through the AutoAgent app.

File-based tuning platforms

Custom tune files are typically delivered by email within 24–48 business hours after all required vehicle information and files have been received. Completed calibration files are delivered electronically by email or another method specified by TWZ.

Refund Policy & Cancellations

TWZ Tuning provides custom digital calibration files created specifically for each customer’s vehicle and configuration. All tuning sales are final once calibration work has begun or the custom tune file has been delivered.

You may request cancellation before calibration work has begun. Once work has begun, or the tune has been completed or delivered, the order is not eligible for cancellation or refund, except where otherwise required by applicable law or payment-provider rules.

If TWZ Tuning supplies an incorrect file or a problem is attributable to the calibration supplied by TWZ Tuning, contact us so the calibration can be reviewed and, when appropriate, corrected or revised at no additional charge.

Customers are responsible for supplying accurate and complete information, including year, make, model, VIN, engine, transmission, modifications, tuning device, stock/read files, and any other requested information. A tune created using incorrect or incomplete information supplied by the customer is not eligible for a refund solely because that information was incorrect.

Nothing in this policy limits any rights you may have under applicable law or the rules of your payment provider.

Order information & payment

We retain order and payment records, the email address and vehicle information supplied with your order, the terms you accept, and tune completion and delivery records. Payment is verified on our server before an order is recorded as paid.

For cancellation requests, calibration concerns, or questions, contact support@twztuning.com and include your order number.
