No Vac at Idle.

[Cody D]

A normal DSM is supposed to be approximately -18hg at idle right?

Mine reads 0hg, and when I give it some gas it does go into vaccum and with my boost controller set normal it shows 8 or 9 psi. It's a brand new boost gauge, my old one showed the same thing.

Anybody tell me what I broke?

It sounds like you either have a vacuum leak or you have your boost gauge tapped into the wrong vacuum line.

If you are not having any drivability issues then I would lean towards the tapped into the wrong vacuum line explanation.

There is a line that runs from the intake manifold to the fuel pressure solenoid to the fuel pressure regulator. Try moving your gauge source to the vacuum line running between the intake manifold and the fuel pressure solenoid.

Let us know how it turns out

Okay, Thanks.
