I'm at my wits end with this car now.
Its a Revo stage 1 S3 amk.
under full throttle the boost is shooting up to 2 bar and then rapidly dropping off to .8 bar.
I have fitted an oil catch can to eliminate oil in the boost system, as well as fit a front mount intercooler.
When the n75 is unplugged the car under full throttle hits roughly .4 bar.
When the Maf is unplugged the over boost still happens.
Does anyone have any ideas or have has this before?
Scans with vcds show no faults.
Exhaust is not smoking at all.
May be a n75 problem? Or my worst fear is a new turbo?
