This product is intended for customers who have already purchased a COBB Accessport and want to upgrade to a JST Performance custom tune. A custom tune can be completed via e-mail or road tuning. Creating a full E-Tune allows us to work with your car's current modification list to create a custom tune specifically for you and your goals! We can incorporate 5 way map switching, FFS, LC, Etc. Step it up even more by purchasing an E30/WMI tune to be included with your custom tune set-up. By adding an E30/RGA/WMI tune, you receive a full 91/93 octane tune as well as the additional fuel tune. Select your tune options from the drop down menu.
*If additional modifications are added (excluding aftermarket turbochargers) during the tuning process, or after completion, a retune fee will be required for any non-lifetime tune customers.
JST Performance now offers a lifetime tuning option. This means that you can purchase our lifetime tune for 91/93 and get unlimited re-tunes for as long as you own your car. Going from Stage 1 to Stage 3? No problem, with a lifetime tune, your covered!*
*Changing or adding another fuel option/aftermarket fuel system or upgrading to a big turbo will require an additional tune purchase unless the big turbo lifetime tune option was selected initially.
*Big Turbo Lifetime tunes only cover tuning on one big turbo per vehicle. If you upgrade your big turbo to another big turbo or stock turbo, a tune upgrade may need to be purchased.
*Lifetime tunes are only valid for the original purchaser of the tune. Lifetime tunes do not transfer if the vehicle and/or Accessport is sold, or from vehicle to vehicle.
