Lets get a list going of all vacuum ports on the factory intake manifold and other areas.

Reason I say this is I think I have a vacuum leak as my engine is hunting and my boost gauge in vacuum goes from 10-12 where as it used to be at around 18.
Also while boosting my BOV will open but will not stay open causing compressor surge.

One thing I did do is disconnect the EVAP and plugged it on the one side, while plugging the ports on the IM that it connected to.

Other than that I can only physically see 4-5 other places taht would connect.


I also blocked off the air pump port that goes on the IM, I know that is not the problem because I have tested that.
