The S63B44T4 evolution of the S63 engine . 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 tuning draws heavily upon our extensive experience with tuning the earlier iterations of the BS63, and our experience with other MG1 ECU platforms, all within safe limits and retaining OEM driveability & integration.
