Chiptuning BMW 550i Siemens MSD85

Another bavarian powerful BMW F10 biturbo with a 550i N63B44 engine running Siemens MSD85. And we have another task to show a good result. The Siemens MSD85 software has been very well studied by our team and working with this control unit is straightforward. As a result, after chip tuning, the car has: power – 476hp/5924rpm versus 386hp/5329rpm and torque – 698nm/3037rpm versus 581nm/3080rpm.
