Yeah, the guys that done my gears was telling me about the valve not being right and the fuel pressure not being exactly right without an fmu or additional fuel. I'm having trouble coming up with a solution there also, cuz i've read that since i have 30lb injectors that it will compensate, that the fmu is for making the stock injectors work harder. But i figured the extra pressure would help. They said i needed to get an adjustable regulator first, and fix the vacuum on my valve. All i know is that my setup is an 11 psi setup and that it only builds about 9 wot. ATI said that was because of the exhaust on my car. But the car makes no boost until probably 3500 or so. So i'm thinkin that maybe i'm loosing boost by the blow off not working correctly. I dunno, and i'm having trouble finding some one with the same setup so that i could get an idea.

Like I said, try to find a performance shop in your area. That would be the best thing to do.

Anyone save the pic? I still can't see it...
From the way it sounds you have a bypass valve & one end should go before the turbo & the other after the tb.
