My other car is a MINI!!!!
I don't want to be rude here, but I think the chap is logging incorrectly.
''most of the time'' to me sounds like driving around normally, during which the ECU will request very little boost so 1010 sounds about right.
if he's done a WOT run from 2-6k and it's peaked at 0.5 bar at just under 4krpm, then that sounds about right to me.
I'm not suggesting it's problem free, I'm yet to see an untouched 1.8T with a working DV and a non split PCV, I just don't think it's running as badly as everyone else seems to think.
being an AUM with a map sensor, to some degree it'll work the turbo to try and maintain boost levels, compared to an AGU which will just see normal maf logs but rich fuelling and pull some fuel out.
