Unleash serious gains from the S63TU 4.4 twin-turbo V8 with this proven Burger Motorsports power module and Boost Control Module combo. This plug-in add-on ECU gives you rapid power delivery, precise boost management and features you simply do not get with a basic remap. It is fully reversible, tailored to the S63TU platform and ideal for drivers who want more horsepower and torque without compromising driveability or reliability.

We have installed and tested this hardware at MJ Modifications and our customers love the transformation. Faster spool, harder mid-range, stronger top end and smooth OEM-like throttle response. If you want a safe, flexible and feature-rich upgrade for your M5, M6, X5M or X6M, this kit is the one we recommend.

Expected results: On standard UK pump fuel many owners see around 100 whp over stock. With higher octane, ethanol blends or WMI, gains up to roughly 240 whp over stock are achievable. The system also supports upgraded S63TU turbochargers.

Transmission note: On DCT cars the factory clutch packs are generally comfortable to around 640 whp before slip may occur. If you plan to exceed this, consider performance clutch solutions from Dodson or SSP.

S63TU map guide

• Map 0: Module bypassed
• Map 1: Additive profile, typically plus 4 to 5 psi over stock, suitable for regular pump fuel, works with or without BCM
• Map 2: Target about 22 psi absolute, BCM required, may approach factory fuel trim limits on some cars
• Map 3: Target about 18 psi absolute
• Map 4: Valet and safety, lower than stock boost
• Map 5: M style curve that ramps boost to redline
• Map 6: User configurable targets
• Map 7: Target about 25 psi absolute for high octane or race fuel, BCM required
• Map 8: Progressive methanol map, peak boost scales with meth additive, BCM recommended

Note: Without the BCM, higher target maps will typically under-target boost.
