got the new gauge aqll hooked up useed all brass fittings instead of plastic (all i had) all plumed with pipe dope and what not and sealed tighttt,,, now when i go in boost the guage will go up and if i hold it on boost the guage will start to go down what could the issue be???

 

lsj's help please

 

maybe it's snagged somewhere on the line? loose fitting?

 

fittings are all nice and tight i dont see a snag any where

 

??????

 

a bad guage

 

bumpppp

 

some one must know

 

Can't be really nothing else other then a BAD gauge or the hose is crimped somewhere... Nothing else can be wrong

 

so if i change the guage or check my linw and its not either or then what would u say do

 

could it not be working right cause i had to use brass to make my t fitting???

 

Then I would say **** it and now worry about it lol

Or get an scangauge and use the boost readings off of that or go back to your stock gauge

 

Maybe it's not the gauge.

AKA check into bypass solenoid or boost bypass valve? One of the threshold's in my tune was causing boost to drop off at redline, we quickly fixed that though.

Do this to check, it's free-

im going back to stock nothign is working

 

That mod is stupid IMO and does it only work if your on a small pulley since it stays on 15lbs and don't drop to 12?

 

im selling everythign noe stock gague here i come yet again

 

could it be becuase that i have to much 1/8 hose just laying around and need to cut it?????????????????????????????/

 

your boost should be climbing the longer that your on the throttle.. I'd say that you got a little leak in the hose from where you pulled it through the fire wall.

 

u think so i cant c it it is think 1/8

 

idk where u pulled urs through at, but i had a hell of a time getting mine.. luckily i got it the first try but I was extremely careful with it.. but I used the plastic fittings that came with mine.. then I black taped the crap out of all of it. check all of it and make sure it's not pinched no where.. if not that, then I go back to saying that it's got a hole in it...

 

no fittings came with mine so i made a t fitting out of all brass fittings but if i put to to 5 psi and try and hold it there the gauge drops slowy to 0 when i know im making boost

 

if you can't feel a power drop, then it's something in the hose.. put a plastic "T" on it and black tape it so that it don't come off.. then make sure that it's not 'pinched' anywhere.. if it's still not working after that, you need some new hose.

 

i had the same issue last time with a diff guage but y go to plastic when my brass fitting is tight and it is not leaking

 

how do u know it's not leaking? if it's not leaking, then that means you got a hole or something in the hose.. I'd just hope for the bad brass fitting instead of having to run a new hose through the firewall..

 

iy only took me like 3 min to run the hose through the firewall
