[quote="rsjohn"]I meant a pic of it in your car so i can see what needle is pointing to!!!!

Sorry no can do John! but to be honest the photo of it in the car would look the same as ubove picture but the needle would be on the 30 inHg.

Also had a play around with it today and noticed that when I pull the vacuum/air hose off from the top of the Dump valve the boost gauge then reads 15 inHg, if anyone has any more ideas! as to what the problem could be please let me know.

CHEERS!!!!
