Description
The Burger Tuning S63TU JB4 Tuner is the most advanced plug-and-play performance solution for BMW M5, M6, X5M, and X6M models. This latest generation JB4 includes breakthrough features never before available to the S63TU platform, including:
- On-the-fly map switching directly from the driver’s seat
- Boost limiting by gear for optimized traction
- In-dash boost gauge display
- Full CANbus data logging
- Built-in fault code reading/clearing
- Integrated progressive water/methanol injection (WMI) control with advanced safety systems
- Optional BCM (Boost Control Module) wiring for direct wastegate control and higher boost precision
On pump fuel, expect power gains of up to 100whp over stock. With WMI and higher-octane fuel, gains of up to 240whp are achievable—enough to push stock turbos to their limits. For upgraded S63TU turbos, the JB4 offers full compatibility, with customers reporting up to 900whp using Stage 1 turbo upgrades.
Whether you’re running a stock setup, bolt-ons, or a flash tune, the JB4 can work as a standalone tuner or in combination to add power, WMI control, and advanced data capabilities.

What is a JB4?
The JB4 is a sophisticated plug-and-play tuning module that installs between your car’s sensors and its ECU/DME, allowing precise control over boost, fuel, and ignition parameters. Unlike basic “chip” tuners, the JB4 integrates CANbus data, advanced safety protocols, Bluetooth connectivity, and flexible map control.
Burger Motorsports continuously develops free firmware updates with new features and performance improvements. The JB4 is not VIN locked, making it transferable between vehicles or resale-ready.
