OK. I have set the Scangauge to show boost by subtracting 14.7 psi from MAP so that is why I was freaking out at the numbers you are talking about. Maybe I should switch to MAP so I get a more accurate reading. Just need to recalibrate my mind so I understand the figures I am reading.

So in general terms cruising at 100kph something around 27 MAP would be good and under load 30-32?
