I know it varies from engine to engine, Boost levels, Throttle position etc, etc. Can someone give me some examples, Ive been for another test drive, 4th gear from about 1000rpm at WOT along a road with a slight incline, At one point it started to pink very slightly.

Im sure it wasnt the AFR as when I looked through the data logs the AFR on boost was between 11 and 13.3
