Boosted b18c1 question... - KCSR

Ok here is my set up b18c1 stock bore/stroke. Professional products intake manifold with omni 68mm throttle body, 550 cc injectors, cast log manifold, turbonetics evolution wastegate 9psi spring with a turbonetics t3 turbo. Running a baseman from phearable.net.

Now that that is out of the way, on the intake manifold I have a number of vacuum ports all are in use for boost guage bov and other normal things, alas I have one thst isn't in use so I blocked it off and it makes My car run rough with a low idle, if I open it up and allow for it to take in unfiltered air my idle goes up and runs fine. I have tried to adjust the idle at the TB to no avail with the vaccumm line plugged. What am I missing? Every thing that should be hooked up is hooked up correctly, in at a loss as what I need to do to get this right before taking it in for the final time any help would be greatly appreciated.
