Right basically the last 2 days I have been pulling my hair out because my car has been showing around 15psi on the boost gauge at peak, now it has just sprung to my attention that when the car is switched off the needle sits at about -9 vac when im sure it should be 0, and when its running its sitting at around -19 vac, so am I right in thinking that with the needle sitting around 9 notches lower than it should when im giving it full whack it should really be showing around 24-25psi and the gauge is buggered, bearing in mind the gauge is around 3 years old and was in the car when I got it.
Somebody please help because if this is the case I am so relived because the car is actually running fine really.
