I know I need a real boost gauge, but i just dont have the money for one right now. I tried the whole disconnect the lower vac line on the BBV and let it suck air and it gave me one bar of boost again, but still no dice. Did the MAP splicing cause a problem? I wouldnt think it would. I checked every t-fitting and elbow for disconnections and found none. The car as I said still runs fine, and the pcm hasnt thrown a code for anything. So i'm out of ideas...
