Clio 2.0i 16V final speed/rotation

Amen, just wrote a thread and lost it thanks to cookie, so the whole again Jo, hello first, am new here in the forum and give me my comment My problem is the following: After a Clio 1.8i 16v and a Megane 2.0i 16v I bought a Clio 2.0i 16v , BJ 2001 , and must say, on the one hand, enthusiastic, on the other hand something seems in my view not to be quite right with the car. The little one is quite happy to shoot, especially from 5000 rpm on he has again e in the power surge, which feels very nice, but unfortunately all this only in the first three gears. Already in the fourth, this slows down somewhat, in the fifth, it is quite bad. As I said, I had already two 16V before, the old Clio I turned joyfully tacho up to 220 km/, the Megane regulated due to speed limiters in the 5th gear at 240 km/h, only the Clio now turns in the fifth from 5000 rpm only very hesitantly high and if it then, after longer start-up time, it reaches maximum 220 km/h Tacho, in my eyes, a little too little and a little too sluggish, on mountains, which the megane crawled up with 210, crawls now at 195-200 km/h…. Can’t be somehow. Is there something lazy or does the box, which stood a year and was now about 3000 km from me gently again, get used to driving fast again? I’m kind of a bit perplexed that the 16v always mute again, I know yes, but I had rotation and speed problems with it. Never before… Does anyone know advice ? Thank you very much S. P.S. and I hope this time he creates the thread
