During a trackday I had this problem, minimum unscrewed itself and go 2000 rpm, can this reduce engine power ?
In addition to this sometimes the plate seems don't move and I have to wait some minutes before I can accelerate.

Yes after only 10 minutes this problem, I'm not lucky, now I regulated the plate, but may be controll pressure too high.

But I want to know if wrong minimum rpm can reduce max speed, only 180 km/h

I don't know, but from acceleration start at about 60 km/h to end of straight after 30 seconds I think I have to reach 200 km/h.

The new suspension setup is very good, Bilstein b6, lowered red springs, swaybars, the roll is very low and feeling good.
Rear spacers reduce understeering.
It would take only light more power on engine.
