Can any of you 7afte guys tell me where I need to run my vacuum lines. I currently have "T" fittings connecting my turbo and wastegate actuator to the BOV, FMU, and boost gauge. The problem is that I can feel the turbo kick in and I know it is making boost, but my gauge isn't reading any boost. Is there possibly a leak in the system or do I just have the vacuum lines crossed somewhere?

Alright guys new problem now. I changed all of the vacuum lines around like you said. They work, but the problem now is that when my car is under boost (and I can feel it boosting) the most the boost gauge reads is 0 p.s.i. At idle it is reading about 10-20 psi vacuum, but I can never get it to go above 0 boost. To give you more of an idea of my setup I have a T3/T4 B hybrid with internal wastegate, FMIC, 2 1/4 intercooler pipes and exhaust, 12:1 FMU. The A/F ration on my gauge reads that it is running just about perfect during acceleration if not just a little rich. My question is do you have a picture of where you "T"'d into the vacuum lines so I can sort of copy that and make it run right? Also, my acceleration is a little jerky so I feel like this has to do with the vacuum lines too. I did put a check valve on it too and I may be having trouble getting it set right. I just kind of wanted to get your opinions in this matter. Sorry about the long post, and any help will be appreciated. Thanks guys.
