Boost Gauge Won't go above Vacuum

[theKnifeArtist]

so i installed this boost gauge i bought. i ran the vacuum line and the electrical wires and all seemed well. i started the car and reved it a little but i the needle wont go past 0. it'll move from vacuum and then stop at 0. i ran the vacuum hose first where the vacuum comes out of the manifold into that factory T, and then i T-ed my line in there. then took off the vacuum line that goes to the little turbo pressure module thing and hooked that up to the gauge and that didn't work. what's wrong? can too much slack in the line cause this? do i not have the line tight enough to the gauge? leak? it has a compression fitting. anything?

well i figured it would at least go to 1 psi with a quick rev to 4 grand. i gave it a little power brake to 2 grand ans still nothin'....
ok..lemme go for a drive around the apartment complex..

qft.

You gotta get on it pretty hard to get boost while sitting, better to take a quick drive.

i guess you were right and i was wrong.
so i went for a little drive around the apartment complex and then realized that i needed to try it on the street, the boost gauge works, i just thought it would be a little more responsive then it is.
but it works. i got it for fifteen bucks...one of those "fell off a truck" deals..hehe...so here i am boosting with my open DDP around town and i bump into three cops! im at an intersection and a cop passes by slowly..oh damn..so i slowly pull out so its not too loud, and look, another cop behind him...he lets me go since i was pullin out so slow...oh great...cop in front, cop in back.. i pull into somewhere i lay low for a couple minutes. then i head out slowly, and i see that one of the cops that actually parked not that far away from where i parked..heads out when i head out. well i made it back home without getting stopped, but whew that was a close one. i didnt have my papers on me either..
but yeah..boost gauge works..cool, thanks!
close thread.

its not that the gauge isnt responsive, the factory gauge is not responsive. but you just wont make boost off the stock turbo without a load, i think the only ones you can are new the ball bearing ones. but anyways, happy boosting

so after i installed it and taped(yes taped, it's temporary, i could have a pod by next week) it neatly to it's position i realized...damn! this shit looks sexy! so i got excited and got snapshothappy.

im gettin some kind of pod with a mount, i dont know quite what it looks like, im guying it off somebody for cheap..i remember seeing better ways of making oversteering column gauges fit our cars...talk to me?

hey my turbo seems stock and i make boost(boost gauge moves) while parked revving around 3-3.5k. then again im a huge noob and im still trying to learn about supras and turbo tuning in general so i could be reading the aftermarket gauge wrong lol. sits at -30 at off 0 at idle and i seen it hit like the 10-15 mark while boosting.

If your gauge is really reading -30 while the car is off and 0 at idle, something is very very wrong.
