i have just installed my old analog boost gauge with a digital boost gauge by AEM.
vacum line is the same location. between the wastegate and the intake manifold (which used to work fine before)

now that everything has been installed, i start my car and the readout is 1. and its a blinking 1. i feel like its telling me some kind of error code that is not in the insturction.
does anybody have had the same issue?

 

I run the aem digital boost but haven't had that issue.Mine reads -18-20'ish at idle( stock cams). Although I also didn't run mine off that location. Have you driven it since? Checking it readings under boost or a decelleration(sp) load? What did you run you wires off of?
