Okay guys... since I installed the kit, I've been running 5psi... I have the T.V.V.C. MBC from Greddy and have been cranking the sucker like 20 clicks or so... The boost hasn't budged... I want to be at 7 to 8psi on pump gas. I rechecked all my hoses and vacuum lines and even reread the installation instructions. I don't see anything that is wrong or loose. Has anyone here had this problem? I'd sure love to be able to boost past 5 psi.

I have the outlet from the compressor houseing going into the MBC and the outlet from the MBC going into the fitting in the side of the wastegate. The opening on the top of the wastegate labeled vacuum is left open to the atmosphere. Am I doing something wrong?

Some help would be greatly appreciated.

p.s. I had a flex section finally welded into the downpipe and damn am I happy!!! I was having bad engine vibration from 4100 to 4200 rpm only and in every gear, just like when I had the solid front motor mount in... My guess is that the downpipe to cat didn't allow enough engine movement... Has anyone else had this problem also?
