Product Details

This plug and play tuner attaches to easy to access sensors in the engine bay and works with your factory ECU tuning to remap your boost, timing, and fueling for optimal performance and reduced turbo lag, all without the risks and expenses commonly associated with flash tuning. 

Includes several performance maps which can be changed using the optional JB4 Mobile adapter/smart phone app, including JB4 maps for 91 octane, 93 octane, E85 mixtures, and VALET/low boost mode.

Installation is very discrete and it quickly removes without a trace when needed. Fuel economy during normal driving is unchanged. Compatible with all driving modes. Made in USA. 5 year warranty.

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.

    Flat 6 Motorsports is proud to partner with Burger Tuning to provide the best piggyback tuning experience to our Porsche fans. Enjoy the customization, power gains, and easy install without worrying about flashing your ECU! 

    Ready to take it to the next level? Burger Motorsports is the manufacturer of the world-famous JB4 performance tuner. We've been pioneering plug & play performance tuning, intakes, and mods for street-inspired race cars since 2007.

    The JB4 is a plug and play tune available for turbocharged vehicles. The tuner installs between your cars sensor and it's DME/ECU (computer) and manipulates vehicle performance through these connections. While it's not the only tuning system that operates this way the JB4 separates itself from the competition with much more advanced connection points and processing including CANbus, fuel & spark control, bluetooth to your smartphone, and a variety of innovative and advanced features not possible with any other system. BMS regularly publishes free mapping and firmware updates adding performance and features as ongoing development allows. In addition the JB4 system is not VIN locked to your vehicle and can quickly removed and swapped between cars or resold at a later time. Often imitated but never duplicated the JB4 has been the gold standard in plug and play turbocharged performance tuning for over a decade.
