i was watching my boost guage and im only holding 16psi till redline...and only spiking 19....doe sthis sound rite???shouldnt i be able to hold like 19psi??
i have a walbro fuel pump also...(its not on my signature though))

 

you should be holding a bit more than that at redline.

Are you sure the boost gauge is accurate?
Did you check all the vac lines on the intake manifold?
are you tuned for more boost? 19 is low to be peaking...


Another guess is from the heat the boost is down a touch so you can raise the boost back to where you had it before. If you need more help shoot me a pm.

Cheres!

 

well i just bought my car like a month ago...and it came wit the mods on my signature....my 2step is set at 6k rpm(stock is at 5k i believe so idk if its tuned or not...yea i checked the vaccum lines and all of them are good...

 

What boost gauge is it?

Where are you located? Like the poster above said, it might be due to heat. What was it boosting when you first got it?

 

well i have the apexi electic boost controller....so i read the boost there...and i live in arizona

 

With the electronic it might be hard to see the spike...Ive never had an electronic but it would seem like the gauge wouldnt be able to react fast enough to show the spike on the display. Where as with a needle you physically see it wrap around...

for example...with a multimeter you can not see an instanteous spike in voltage with a digital, but you can with an analog...make sense?

 

yea...well it shows peak boost...well idk how to tune it so theirs the problem.....
