Ok.....where exactly does the boost gauge hose hook up to? the BOV line to the intake manifold or the pressure sensor. I'm only reading about 6 psi of boost hooked up to the BOV.

 

Just tee the boost gauge into the pressure sensor and bov from a vac source on the manifold (I use the nipple on the left of the BAC.

 

ok...as far as I can see, there are two nipples coming out of the UIM. One to the right and one to the left of the BAC. Right now, my BOV/boost gauge are using the nipple on the left. The one on the right is the one that the pressure sensor is hooked into.

 

what mods do you have on your car??? I have a Intake and cat-back and im only running 4-5 PSI and i have a autometer boost gauge. I just T'd mine into the pressure sensser.
