Burger Motorsports S68 JB4 Performance Tuner - BMW G90 / G99 BMW M5 S68 4.4L

JB4 takes your G90 BMW M5 from factory stock to full race-ready performance, offering unmatched tuning capabilities. Designed for easy installation and complete removability, the JB4 requires no splicing or cutting of factory wires, making it the ideal choice for your S68 engine. 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, 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.
