Burger Motorsports s63tu M5/M6 JB4 BETA w/ BCM & OBDII
Our latest kit for the S63TU M5/M6/X5M/X6M, the new JB4 includes functions never before available to the platform including on the fly map switching, boost limiting in lower gears for improved traction, an in dash boost gauge, full CANbus data logging, code read/delete, integrated water/methanol tuning with progressive safety systems, and the ability to tune for as much boost as your octane and/or fuel system will allow. For most running pump fuels expect power gains of around 100whp over stock. For those who really want to push the factory turbos with a water/methanol injection kit and higher octane fuel power gains of up to 240whp over stock are possible. The JB4 also supports larger S63TU turbos. We've had customers report as much as 820hp to the wheels using simple Stage1 turbos! The JB4 is absolutely the most flexible and easy to use tuning solution for thes63tu platform and is even compatible with cars already running flash maps who want to add more power, WMI control, or extra features to their tuning.
