Shawn - there are 3 speed limit configurations on the 550i:
1) 200kmh - Stock 550i
2) 250kmh - 550i M-Sport
3) Unlimited - 550i Dinan
It is possible Wert_02 is the M-Sport setting and not the unlimited setting. I am curious whether MJGood has a Dinan or just an M-Sport. Mine is M-Sport and Dinan.
If Wert_02 raises the limit to 250, then it would suggest that maybe Dinan is delimiting the car somewhere else or perhaps their software overrides the car's software.
