BMW M2 M3 M4 Tuning F80 F82 F87 S55, you can expect to see figures of around 530 BHP from our stage1 ECU calibration right up to some serious numbers with our stage 3 performance upgrades…power, and reliability you can trust.
S55 power output ranges from 410BHP and 550Nm in the M2 Competition up to 500BHP and 600Nm in the M4 GTS. The GTS did have some modifications including a water injection system to help keep charge temperatures down. However, over 500BHP is easily reliably achievable out of the S55 engine without any modifications with our custom BMW M2 M3 M4 Tuning packages.
The S55 engine is BMW’s high-performance variant of the N55 engine. The design changes included a revised closed deck block design, forged and lightweight rotating assembly, twin fuel pumps, revised cooling system including charge cooler, and most importantly the addition of an extra turbo.
