The JB4 tuner for the Toyota GR Supra Mk5 is the most advanced plug and play tuning system available for the turbocharged Supra platform. Power gains of up to 80 horsepower to the wheels (100hp crank) are possible on a completely stock vehicle running pump gas with the B58 engine.

No ECU flash required and fully compatible with locked 🔒 ECUs.
The JB4 features a simple plug and play installation harness allowing fast installation and removal while delivering advanced tuning capabilities unavailable with other tuning systems.

What is a JB4?
The JB4 is a plug & play tune available for turbocharged vehicles. The JB4 tuner installs between your car's sensors and its 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.
