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 to your JB4: Grab one of our smartphone connection options to wirelessly connect the JB4 BMW tuner to your Bluetooth 4.0 compatible iOS or Android device. 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.

JB4 Mobile by DMAC was released in 2014 and has become the gold standard for phone-to-tuner integration with its unique gauge display options/themes and advanced security systems. The JB4 Mobile app is purchased separately for $29 and requires the JB4 Mobile adapter.

JB4PRO by Burger Motorsports is our brand-new in-house adapter designed from the ground up for ease of use and reliability. Our new adapter fits fully inside the JB4 enclosure for enhanced weather protection and a more streamlined look. The JB4PRO Free app features an intuitive easy-to-use interface, help buttons, and advanced log analysis tools that can estimate the performance of your car and help identify any tuning concerns.
