Did a couple searches, but didn't quite get an answer to what I'm looking for.

Currently, my gauge only registers Boost, and I want it to register Vacc also.

How do I hook it up? Thx.

How do you have it hooked up now? All you have to do is tee it into an existing vaccuum line and it reads boost and vaccuum.

I have the clear boost hose going to the sensor which is on the intake arm coming from the turbo, into the throttle body.

T the boost gauge into one of the vaccum lines on the intake manifold like the FPR line or the cruise control line (if you have CC).

It's not going to read vacuum until you hook the gauge up to the intake manifold. T off the Fuel Pressure regulator or something on the manifold <after the throttlebody> to get the vacuum and boost sides to work accurately.

thats what I thought.. just wanted other opinions.

Thanks guys

My boost gauge hose is a real hard plastic, do i need to get a coupler to T it? Vaccum T's i dont think will work... this hose aint stretchin

SiR Kid

Use a silicone hose and a fitting on the back of the gauge... forget the hard plastic BS that comes with the gauge...

the boost guage has to be hooked up somewhere between the throttle body and the head
