I finnaly took her out with the the mile long list of new mods....the most prodomanant problem is no boost with the vortech s/c trim... i boosted it to 5 lbs at idle....but when i drove it ...i didnt see any boost...not sure if the rpms were high enough though...but....may i have a vacume leak or pcv problem that can be causing this?? i thought about caping the pcv inlet on my typhoon intake...and running the pvc to the valve cover while teed off to the intake air filter inlet....would the pcv cause the boost leak??? thankls

im guessing vaccum leak cause at closed throttle (idle) you have boost once air enters after throttle body plate it all drops off. check the basics like vaccum lines and connections on the intake, and the vaccum tree. (charcoal canister, pcv, fuel regulator, egr, b/s). if that yields nothing shoot some either around the base of the lower intake, if the car revs thats where you have a vaccum leak.

How tight do you have the belt?

before tightening the belt more, i saw 1 lp of boost...after tightening it down i now get 2-3 lbs...but i think it is still not tight enough...also i checked the vacume on my vacume / boost gauge...and the vacume falls off fairly steady!...i know i didnt put thread sealer on the back of the gauge....could this also be a problem with losing the boost???

yeah first thing is make sure your guage is actually working properly. For the oil in the intake disconnect the line from the TB to the valve cover first and see if that resolves it. If not then the oil is creeping up the PCV line and disconnecting that will stop the oil but. You shouldn't be getting that much blowby in the first place so double check your firing order and it might be time for a hone and new rings.
