Take the performance of your JB4 equipped vehicle to the next level with a custom backend flash! At Boost Addictions we recognize that properly tuned vehicle should not only be fast, but smooth too. We work to optimize the parameters your vehicle runs at based on your given fuel and modifications to provide reliable and consistent power. These aren't canned tunes, and are optimized for every vehicle we tune. We will also offer unlimited revisions as the fuel type remains the same.
