I need a new Boost Gauge for my 05 grand prix. the one i installed were my midle air vent used to be isnt working at all. all it does it pick up vaccum and doesnt register boost. im assuming its the gauge unless somebody thinks its hooked up wrong and wants to look at it.
only thing that would make it not work would be a check valve on the vac line, or the gauge is bad…
OK i am looking for a new boost gauge. it needs to be 2 5/8". would prefer a red back light on it but will take anything at this point…
Iv got one, pmed.
