Ready to take your S63TU to the next level? 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 900hp to the wheels using simple Stage1 turbos! The JB4 is absolutely the most flexible and easy to use tuning solution for the s63tu 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.Installation is fully reversible attaching to the TMAP sensors and OBDII port. The included BCM wires are optional and allow the JB4 to take direct control of the wastegates for more precise boost targeting for higher boost maps.The JB4 is a fully plug and play device that installs and removes in minutes at home without special tools and unlike flash maps that permanently write over your DME with the JB4 your DME is never aware it's running more than the factory power levels. And when you're ready to change things up the JB4 is not VIN locked and can be moved to your next vehicle or resold. For those running a DCT transmission we've found the factory clutch packs are only good for around 640whp before they start slipping. If you are planning for more power than this plan to upgrade to Dodson or SSP clutch packs sooner or later.
