    Question Boost Gauge Rattles at 7+psi

    I installed a Delphi gauge in my girls wrx and everything works just ****, but at full throttle it rattles and hums like its all pissed off. The install is correct, I followed instructions posted on this board. I'm starting to think the gauge is defective, but hope its just human error.

    Whatcha think?

    I got the VDO boost guage, and to me it seems like above 10 psi it might be leaking from the hose in the back....

    I dunno, maybe i didnt tighten the hose enough....

    If it's mechanical check the hose....
