Sooo I've been having a boost gauge problem for the past month (Prosport electronic) and it's starting to piss me off like no other. First off... The problem i'm having is that everything turns on ok.. Gauge sweeps at start-up but then once the car is idleing, the needle sits at 30in of vaccumm!!
Actions i've taken so far:
1) Checked over wiring - no loose connections found at this time.
2) Thought it was the sender - Ordered a new sender from prosport. Installed sender and it did not fix the problem.
3) Called Prosport - Sent my gauge and both senders (Old one and the new one). They tested everything and told me that everything tested out ok and that there must be something wrong in my wiring. They sent me a new wiring harness that goes to the back of the gauge.
4) Today.. I completely re-wired my gauge. Everything is wired up and getting power but still has the same exact problem. When re-wiring I used the new harness they sent me, and I used the new sender w/ new sender harness.
I really don't understand this.. And now i'm trying to decide if I should just order a whole new gauge from Prosport ... or maybe try a new gauge manufacturer???
Only problem with the new manufacturer is i'd have to completely re-wire that gauge because obviously the connectors anen't interchangeable.. Most likely i'll get another Prosport and hope for the best...
