BMW N63TU3 ECU Tuning X5, X6, X7 M50i, M550i, 750i, M850i

STOCK: 530BHP --> TUNED: 680BHP STOCK: 553FT/LBS --> TUNED: 626FT/LBS The N63TU3 evolution features many of the same engine components as the 'M' version S63 limited by the single scroll Turbos. 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 tuning draws heavily upon our extensive experience with tuning the earlier iterations of the S63, and our experience with other MG1 ECU platforms, all within safe limits and retaining OEM driveability & integration.
