Terms and Conditions

REGULATORY DISCLAIMER

Many states prohibit tampering with a vehicle's emissions control equipment. ECUMaster and WHP products are designed and intended exclusively for sanctioned off-road or competition use in non-emissions-controlled vehicles. They must never be used on public roads or highways unless a specific regulatory exemption applies.

Using ECUMaster/WHP products on public streets or highways is unlawful unless permitted by applicable laws or exemptions. For detailed state-by-state emissions compliance information in the USA, please visit the SEMA Action Network website.

It is the sole responsibility of the installer and/or end user to ensure compliance with all relevant local, state, and federal laws and regulations. Always check with your local vehicle authority before purchasing, installing, or using any ECUMaster/WHP product.

  • All orders with mismatched billing and shipping addresses will be canceled unless the following conditions are met:

    • A seller-protected payment method, such as PayPal or Shop Pay, is used.
      (If Shop Pay does not confirm Seller Protection for your order it will be canceled.)

  • To ensure security, orders deemed potentially fraudulent or risky may be canceled at our discretion.
