STOCK: 553BHP --> TUNED: 710BHP STOCK: 502FT/LBS --> TUNED: 656FT/LBS The S63B44T0 and S63B44T2 4.4 liter V8 engine in the X5M and X6M packs a powerful 547 hp and 502 lb-ft of torque. The most powerful AWD platform BMW has ever made. But as with all modern vehicle platforms the output is limited by the manufacturer in order to leave headroom for performance improvements in later model years. Our BMW F10/F12 tuning draws heavily upon our extensive experience with tuning other Bosch MEVD & MED17 platforms such as Jaguar, Aston Martin & our World Record Setting McLaren 570S package developed in partnership with Johnny Bohmer Racing. Our Software increases crank output by 157BHP and 154ft/lbs of torque, focusing on mid-range RPM power deliver, seamless integration into the factory software. The result is a huge increase in performance, throttle response and driver enjoyment. DYNO DATA ATTACHED FROM AN M5, AND AN M6 GRAN COUPE WITH COMPETITION PACKAGE - STARTING AT 600BHP. FINAL OUTPUT WILL BE THE SAME FOR NON-COMPETITION PACK MODELS
