Burger Motorsports JB4 Tuning Box 2020+ Toyota Supra Mk5
Power gains of up to 100hp on a stock vehicle without the risks of flashing!
Units shipped 3/5/2021 or later include a free electronic wastegate (EWG) connector preinstalled in the JB4 harness!
The JB4 is the most advanced and highly featured tuning system available for your Toyota Supra Mk5. Power gains are up to 80hp to the wheels (100hp crank) on a completely stock car on pump gas for a B58, gains with bolt-on parts, higher octane, E85 mixtures, and larger turbos are even higher.
The JB4 features a simple plug and play installation harness for easy installation & removal and includes many features not found with any other tune. Including on the fly in dash map switching between factory and various performance maps, optional in-dash gauge displays for boost, boost limiting by gear for improved traction in lower gears, progressive water/methanol support, built-in data logging, built-in code reading, optional direct EWG control to prevent throttle closure with exhaust modifications, exhaust flapper control, and much more. Other more expensive tuners may claim to equal the JB4’s technology but upon closer examination lack most if not all of the JB4’s features.
Remember the JB4 does not require any additional modifications or previous stages. Simply install the JB4 as your first and only modification and enjoy an entirely new fast and smooth racing experience. The JB4 also does not require any user setup or customization but for those who are interested in logging, adding new features as we post them, etc, we suggest the BMS DATA cable or REV3 mobile phone adapter.
Note we have not developed the in-dash commands yet for the JB4 Supra. Until then a JB4 mobile adapter or BMS data cable is required for any map and setting changes.
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.
*Power figures quote can be dependant on a number of factors including JB4 map settings, fuel quality, engine history & health, extra performance hardware added and ambient atmospheric conditions the vehicle is operating under.

The JB4 is a plug & play tune available for turbocharged vehicles. The JB4 tuner installs between your car’s sensors and the DME/ECU (computer) and manipulates vehicle performance through these connections making your vehicle much faster. 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 be 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.
