When I was driving on the German highways I noticed that mij turbo engine didn't go faster than 160 km/h. It wasn't possible to get it past 4000 rpm at full boost. The fuel presure is around 5 bars at this moment.
In other gears than fifth I can get over 4000 rpm. In fifth at these rpm's it heats up for about 10 degrees C.
Anyone ideas what the cause could be?
