We've revamped our tune file processing system! After you place your order, you'll receive an order confirmation email that includes a tune form to fill out out your vehicle. You can also view this at the top of the website. This helps us get all your tuning information in one place to process it quickly.

**If you purchased an EFI LIVE License ONLY for $125, you are confirming that you already have a flash device (AutoCal or FlashScan). If you do not know what either of those are you need to select the AutoCal Device + EFI Live License option to flash your truck.
