read your message on the thanks you gave me, can you take a picture of your dash and send it via PM to me?
A boost gauge is typically marked 0 to 40, 50 or even 60. Mine is in the lower left side next to the oil pressure gauge. As your engine load and fuel increases, the boost gauge should increase from 0 to perhaps 25 PSI.
Is your engine blowing any black smoke? If yes, that's an indication of insufficient air getting into the combustion chambers (bad air filter, bad turbo, leaking fitting or intercooler, etc.)
