Hello ! rides a 94 Audi 80 Avant with ABT engine (2.0 90hp). was last time at night on the AB … and well I drove full speed. it is registered with 180 km/h vmax, should therefore make tacho 195. have even heard of some that they have managed 205. however I just came dry over ~180 km/h. road, no climb, no headwind. how come?! motor so gloomy that he can not faster!? of course already from the free bubble possibility ho rt (100km at the piece full gas) just I don’t want to do that to my soon 14 year old engine somehow. so what do you think you can do to make it come back to speed? achja turned off the engine is also long no…he was so at 5000 rpm. MfG
