The ultimate tuner for your S55 powered vehicle, the JB4 allows you to go from factory stock to full race, and everywhere in between, with the push of a button on your steering wheel or phone. The JB4 installs and removes easily and includes many unique features not found in any other tune including user adjustable 1st and 2nd gear boost limiting, map switching in dash, electronic wastegate control, ethanol fuel support, and built in advanced CANbus based diagnostic tools. Installation is completely removable with no splicing or cutting of factory wires.
The JB4 is compatible with the factory flash map, competition package flash map, all off the shelf flash maps, custom tuned flash maps, or any flash map you choose to load! For those who don't mind flashing BMS provides free back end flash maps designed to optimize performance for specific builds and fuels saving you hundreds of dollars and many hours of time on custom flash tuning.
