Power gains range from 30-60whp on pump gas and much more on higher octane or E85 mixtures.

This quick install plug and play tuner connects to easy to reach plugs on top of the engine and safely increases turbocharger output by 3-6psi producing significant power and torque increases. Timing and fueling are appropriately rescaled for the increased boost and the installation is completely reversible in seconds. Compatible with all-wheel drive and rear-wheel drive models. The JB4 is the only tuning system that includes CANbus and optional wastegate connections providing dramatically improved performance and smoothness over other 2-channel tuning systems.

Wirelessly connect the JB4 to your Bluetooth 4.0 compatible iOS and Android device via the JB4 Mobile connect kit, or to your Windows laptop with the BMS data cable. Both options allow you to record and analyze vehicle and tuning data, change JB4 performance maps, and update JB4 firmware as we release free newer versions with updates, more powerful maps, and new features under development. Separate JB4 Mobile app purchase also required.
