not building boost, need help fast

[Tsi_User]

first off this is on my friend's 95 Tsi AWD with a t25 and an aftermarket boost gauge

He was running stock intercooler piping with a SSQV and was getting a full 11 lbs of boost on the car

today we started to upgrade that setup, we installed a full aftermarked UICP with a greddy type-rs BOV. The BOV was set to the lowest setting when we put it in, to we turned the adjustment knob around once and tested it out...no boost. We forgot to tigten one of the coupleings, so I tightened it, adjusted the screw on the BOV one more turn, we get 5lbs of boost but then it hits a wall. Turn the BOV again, 5lbs of boost, hits a wall.

So now he's stuck with just 5lbs of boost, I know we should get a boost tester and check the intercooler couplings, but we don't have one on us right now and we need to get it running tonight. What do you guys think it might be, just a leaky coupling on the UICP or what?

Most likely yes. Or the bov is not setup correctly, I'm not familiar with rs sorry can't help you there.

definately a leak in one of the couplers

I don't know if you guys know much about the RS since it's new, but according to my friend the RS says somewhere in the instructions that you might have erratic boost problems if you aren't using an aftermarket MBC

He has an MBC, but I figured we'd install the UICP, BOV, test for leaks and then put the MBC on it.
