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.
