JB4

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 smart phone, and a variety of innovative and advanced features not possible with any other system. Often imitated but never duplicated the JB4 has been the gold standard in plug and play turbocharged performance tuning for over a decade.
