Does any one know how much boost a focus st should make?

The boost gauge goes up to 1.2 but i know 2 people who say it only moves about quater of the way up the gauge which would suggest only boosting about 0.3.

Any info would be good

mine used to hold at a quarter, then shoot off the gauge for a few seconds then nothing. turned out the wastegate was knackered which involved a new turbo.

My standard car boosts to just over half way when over 3000 rpm.

If will hold about a quarter of the gauge below this RPM.

I am failrly sure the stand car runs a max of 0.5 bar (7 to 8 psi)
