I drove yesterday with my Fiat Punto 1.9 jtd with 80 ps about 30 km on the highway and was all the time in the 5th gear, pedal fully penetrated and as usual it went from 140-150kmh no more really ahead. I drove so whole time with crossed pedal and all at once he had from one to the other a power increase of the very best, then was in the shortest time to 190kmh. When I released the pedal again and he was again so on 140 he Run like always. Has happened to me in the last week 3 times. But if net depends on the speed or something, is really totally unpredictable. May be that something is clogged on filter or lines, or maybe something is wrong with the turbo, because it generally seems to me as if the speed for 80ps is much too slow. Should maybe also say that I have a blackbox in it, should supposedly bring 20ps more of it you notice but net really a lot, Feels more like 5ps, can also be that the thing has a Macke somehow. Has one of you ever had similar problems, or knows what is lazy? Thank you already in advance
