Q: the car is limited at 250 km/h. if i can take the limiter off with what speed will the car run ???
A: Yes you can. Dinan sells software that will do this. They don't say what the top speed is, but you have to call them anyway just to buy the software, so you can ask then. I would guess 175 (280) instead of 155. The software also raises the redline 200 RPM for manual and 100 RPM for SMG along with some other tuning that increases HP by 8 at 6500 RPM. All for only $499! http://www.dinancars.com/store/Performance-Engine-Software-2007-Models-c-437-p-2753.html
