Sorry, että kysymys on "sohon"slangilla, mutta voin kääntääkin sen jos joku ei ymmärrä.
Itsellä ei ole kokoemusta "softista"

Friend of mine who is driving old 900 soft TURBO (year 1990) asked me for help yesterday. He has a feeling that the turbo doesn't work and the car is missing this kick off feeling around 3000 RPM. I was driving the car for a while, to me it seems that it still has a lot of power, there is no strange noise from the engine, starts are OK, engine seems to run OK from 0-5000 RPM, no water or oil missing. This soft turbo models do not have turbo pressure indicator on the board. Do you think that there would be any warning signal from ECU on the board when something is wrong with the turbo itself?
