booooost

so take all three of the vac lines off?

Did you also spray carb cleaner around your lim and the valve covers?

3? no there is ONE vacuum line you take off. the RED one in the diagram.

I'm gonna bud in here. If you want a proper vacuum line diagram just Google Image 'Grand Prix GTP vacuum line Diagram'.

there are 3 T's. where do i stick them? i took the vac line out and left it, and took the wire harness off and the boost was working as it should. but im not sure if that is correct. i just googled it and nothing really came up. I'll do it again.

Wrong. That will show exactly what he has stock. He needs to remove the red part only I drew. just take the ONE T off thats on the Fuel rail. and the vacuum line that goes into the passenger side of that T, hook it up to the Fuel rail. Problem solved.

Hey i have the same problem. So what do you hook the pressure regulator to after you disconnect that line from the BBV

I think your suppose to leave the red line dissconnected leaving the boost solenoid/sensor disconnected & unplug, or like you said hopefully someone will help out im not to positive.

So, the fuel rail has that little cap right? do i just put the vac line into that? if so, how is it supposed to stay in there without falling out or spraying gas everywhere?

after removing the T from the FPR and the vacuum line that goes under the supercharger snout thats the passenger side of the T on the FPR right? Do what with the passenger side vacuum line from the T on the FPR, How do you hook it to the fuel rail?
