This product is intended for customers already running a JSTuned ProTune who have decided to upgrade to our Unlimited Tune option (unlimited tunes will be applied to the turbo choice originally purchased, i.e. if you have a custom tune for stock turbo, this item will upgrade you to a stock turbo unlimited tune). After purchase, please email our tuner at firstname.lastname@example.org using the same email chain that was used during previous tuning to notify us that you are ready to begin revising your tune.

*Don't forget to throw in a set of NGK Spark Plugs when you order your custom tune! Upgrading your spark plugs or simply changing them out to a new set is just one step to ensure that your car is performing properly during the tuning process!
