Power gains from 70hp and 100tq to the wheels on a stock vehicle without the risks of flashing!

Power gains of up to 120whp and 160wtq bring the car to life allowing 1/4 mile potential deep into the 10s. Unlike other generic tuning devices, the JB4 includes full CANbus integration via the OBDII port for advanced tuning, safety features, and diagnostics, as well as electronic wastegate control for superior boost targeting. This is simply the best tuning box available for your Audi.

Installation is fully reversible, attaching to the TMAP sensors and OBDII port. Firmware updates loaded via JB4 Mobile or a BMS Data Cable will be provided for free as we expand the JB4's performance, maps, and features with future development.

Wirelessly connect the JB4 to your Bluetooth 4.0 compatible iOS, and Android device via the JB4 Mobile connect kit or 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. A separate JB4 Mobile app purchase is also required.
