JB4 Performance Tuner

The Burger Motorsports JB4 Performance Tuner is a plug-and-play device designed to remap boost, timing, and fueling for optimal performance in turbocharged vehicles. It connects to existing sensors and works with your factory ECU tuning to reduce turbo lag. The JB4 features a programmable CANbus system, upgradable firmware, and data logging capabilities.

This tuner offers advanced safety features, such as maintaining low boost until the engine reaches operating temperature and reducing boost if the engine overheats or knocks. It includes maps for 91, 93 octane, and E85 fuel mixtures. The JB4 is designed to be discreet and easily removable, leaving no trace.
