Hello After I have been declared stupid in many forums again and again, I turn to you. My uncle bought a 964 Carerra4 Cabriolet Bj.92 2 years ago. Of course, after such a purchase everyone wants to know what the part is going on. So off on the highway. It was a Sunday in the summer 3spurig and free. The tacho showed after a few kilometers definitely 290Km/h. No matter who I tell that, it comes again and again: There you dream of or impossible ect. Yes is the tacho wrong od Last year we left an S4 with this thing. Yes the reaction to it : Dream on and partly also insults. Slowly I get really stupid. Either the box from the uncle is tuned or the 964s are just so fast. How do you see that? Thank you.
