Just like the title says, it won't read over zero when I'm under boost. Now, how I have my vacuum lines setup...I have a line that connected to boost gauge of course and I have that line connected to a tee barb that also connected to BOV which is connected to the intake mani. Could this be the reason why it won't read over zero? I have I my gauges wired to my 12v source (igintion wire) per a forum on her that I read on here. So any help would be appreciated thx
