Good to seee you fixed it. Well I think I know the vacuum port you're talking about. On my B16 and my friends B16 there;s a nipple for a vacuum line its the highest vacuum port in the center of the T-body. I T'd my boost gauge there and the gauge was readin backwards the port is for the charcoal Canister and emissions BS But I took all that off But if you hook the MAP line up to it the car will run and idle like CRAP. I have my MAP line T'd into my Fuel pressure regulator.

I was getting weak Vacuum from the MAP port and even took my T-body off and ported out the hole thinking it was clogged so still weak Vacuum. But the FPR vacuum sorce is great so thats where I have to run my MAP sensor. Everyone looks at it ands like dude you MAP ran wrong and I have to explain ths situation. But it works fine the way I have it ran so I'm sticking with it.
