Limited Lifetime Warranty

Factory Direct Limited Lifetime Warranty


All Hypertech Power Tuning Products are warranted* against defects in materials or workmanship. Hypertech’s liability under this warranty shall be limited to the prompt correction or replacement of any defective part of the product which HYPERTECH determines to be necessary. This Limited Lifetime Warranty is to the original purchaser for as long as he or she owns the vehicle on which the product is originally installed, providing all the information requested is furnished. You must retain a copy of your original sales invoice or receipt. Without proper documentation, a service fee will be applied. Resold units are NOT covered under this warranty.

Return Your Vehicle To Stock Tuning


BEFORE Taking Your Vehicle In For Service


If you take your vehicle to a dealer or mechanic for service, you must first remove the Hypertech Power Tuning and restore the stock programming. This is because diagnostic devices expect to find stock calibrations and will often overwrite the program if the latest stock calibration is not found in the computer’s memory. This will result in the loss of your Hypertech Power Tuning data. The Power Tuning can be easily removed to restore the stock tuning before you take your vehicle in for service, enabling the service technician to upgrade your stock calibrations. After the service is complete, you can reinstall your Hypertech Power Tuning. If you have any questions related to service issues, please call Hypertech at 901.382.8888.



The REACT throttle optimizer features an easy plug and play installation giving you access to full throttle customization in a short time. The set up is automatic and a magnetic mount is included. No warranty is voided with the installation. If you have any other questions please give us a call.
