turbo or gauge problem?
i just finished installing my gauge, and while i was driving the highest it went was 5 psi and after 4500 it dropped entirely back into the inhg range, it stayed around 20ish during idle and maybe 15 on cruising. even when i felt the jolt of the 2nd turbo it still just went down. i'd like to think it's not the gauge but what could it be. i have it hooked up to the map sensor line and it's grounded to the body from a bolt near the clutch, haven't hooked up the illumination wire yet though.

i'll do that tomorrow, it's a mechanical ground though, would the location have any effect on the gauge or is it just for the illumination? i'll try tapping into the uim instead of the map sensor and see what changes.

thanks, i'll give that a shot. Just to clarify though is the map sensor line more accurate or in any way better? I remember when i searched i found a number of old threads that said that and i just want to make sure for myself. thanks again for the help
