With this process and product being brand new on the market, your specific truck may have a more recent software that our calibrations database does not yet have tunes to support. In such a case, upon your initial update you'll be prompted with that information and our engineering and calibration teams will generate the required files for you. Please allow 1-2 business days for our calibrations team to add support for your vehicle. Your tuning device will not be able to unlock your vehicle until support is added. Once the support is ready, our system will email you and your device will be able to download the updated support via Update Agent for immediate unlock/flash tuning.
