This tune requires you to mail in your DME for the initial flash. If you plan to get our flash cable in the future we can do what is called a bootloader change which is a one-time software change that allows for OBD2 port tune uploads. Please select the bootloader change option if you want to get our flash tablet set up now or in the future. Each map change takes under 2 minutes. This will allow you to turn on and off burble, cold start, switch between stock and your performance tune, and/or any other options we offer for your DME. Please see our DME Tuning info tab at the top of this page for more information. In the modification box, please specify all current vehicle modifications and desired options.
