Boost Gauge Problem

[dphair05]

My boost gauge in my 05 LGT always reads max PSI. I checked all of the connections and they all seem to be alright. The vacuum line is also completely fine. I was just wondering if the gauge it bad or if there is something that I'm just not checking. What do you think?

get your hands on another gauge and see if yours is accurate. how much boost is it reading on your gauge?

I know it's not accurate because right when I turn my car on it goes right to 28 PSI. No matter if the car is just idling or im on the hammer, its at 28 PSI. I'm starting to think the gauge is junk.

yeah the gauge is no good

One of my friends said something about the vacuum line being messed up. Is that possible even though its reading 28 psi
