In addition to a tuning device, every vehicle requires a specific number of HP Tuners Licensing Credits in order to unlock and tune the vehicle’s modules. Customers who need credits added to their RTD device can choose the exact number of credits needed from the drop-down menu during checkout.
If you are unsure how many credits your vehicle requires, please visit:

Please note that most vehicles require credits for multiple modules, including but not limited to the ECM (Engine Control Module) and TCM (Transmission Control Module). It is extremely important to ensure that you purchase the correct total number of credits required for all modules you intend to tune prior to placing your order.
