Hello, will probably still be theme starter of the month. ..but a new car also raises questions. Just come back from the Harz to reach times on the A395 Vmax. The highway has long gradients. The SD4 makes max 203 km/h and is then again slower despite persistent gradient 202, 201. I tried it in the fifth as in the sixth gear. Here in the forum there are some SD4 driving that can create >215 km/h, supposedly even GPS measured. That a car with 190hp not slow further n the front is crawling, like for example a Q3 is already strange. Weight and cabinet wall to or from. The throttle is not as if you are driving against a wall and suddenly the thrust is off, because it is going slowly from 180km/h anyway. But does it seem to me somewhat regulated. Can it be that from MJ 2015 a Vmax is stored in the control unit? Should someone have experience, can you have that lifted with RR or a tuner?
