I am inclined to mistrust your stock vacuum gauge.

If the vacuum gauge is reading identical to your boost gauge, you almost have to be running on 1 rotor or it should rev up really fast.

Thanks NoDOHC, the gauage is aftermarket and i am starting to believe it might be operating on one rotor(fuel injector not pulsing). The reason i state this is because the car is hard to start(unless i play with the pedal) in addition to several turns of the key. When it does start it sometimes sort of stutters then rev good but the rpms drop then hop back up, then drop, then hops up again. This shit is getting on my nerves!!! When the car warms up at idle its does the same thing...hops from 1000 to bout 1600-1800 then back down to 1000.

What freaking me out is that the compression is 85psi front and rear, fuel pressure is good, no flooding, oil pressure good, plugs clean, oil clean, af meter reading good, once running revs up quick when i hold the pedal however the rpms will drop then come back to where it was previously.

This car is a common swap:
84 gslse, 87 TII(s4) complete pass harness(nothing was cut) still connected to the motor,drivers harness made and continu test done(ends tested), walbro pump, stock ecu, 87 TII tranny(still shopping for driveshaft).
