Gear ratio

I wonder if there’s something wrong with the engine control. If I blow it up (white up 75ps) from lower speeds up to the 6.oooU/min there’s a , two areas where it gets somehow more air than fuel…there’s some lack of passage (if you can speak of passage at 97NM torque at all) … The real problem, however, is that in order to get to top speed, I have to blow the kid up to 175kmh in 4th gear and then in 5th gear. ng the speed can only be kept on a flat motorway and can still increase (sometimes on the A5 behind Karlsruhe), until then 185kmh on the clock stand… There is a problem with the engine control, the injection or the like before or is this simply a shitty transmission installed, because I can therefore save the 5th course for hunting as well as so well… Thanks for hints and tips. The VW Fritze on site is great, however, I have no time and desire with the around, because the anyway “experienced ” The Wolfsburgers have to collect until they officially let something out…
