I assume you are stock, so you should ussualy be around 10 psi, climbing up to 12ish in the higher RPMs in 2nd and higher

NOw if you are only seeing like 8 or less in most conditions, and peaking at 10 psi than that seems low

seems a little low. I have a CAI and AEM filter and always see above 10psi at WOT unless im bogging the motor down or something below 3k rpm. Even above 90.

stage 1 cobalt is 10psi (12 on a cold night)
ne thing way below 10... u have a boost leak or ur vacuum isnt working right
but usually u run below 10 psi if its a humid day... all cars run shitty on a humid day

WRONG!

A stock cobalt should be peaking @ 12psi.. if you're lucky, under perfect conditions you might see 13psi
@ WOT in 2nd gear, if you don't hit 12psi then your car is messed up, or there is something wrong with the boost gauge

Stage 1 is the same pulley, therefore the same psi, as stock. The only diff. is the injectors and tune.

As we have said, 12 psi should be seen at higher RPMs (under WOT) in 2nd gear and up.

Depending on your driving style, you might not hit 12 often in daily driving. Find a nice stretch of road that you can pull all the way through 2nd, and a good ways into 3rd.

If you are not getting beyond 10 psi at all than something is up

I'm hearing alot of strange things about stock psi. Depending on where you are will effect it slightly. However you should see 12psi peak. It also should be peaking quickly. When my car was stock I could easy hit 12 psi in first gear.

Or something is very right. I have finally killed every last bit of wheel hop and can finally go WOT in first after I get hooked up (above 3k ussually). It's a great feeling.

read my post once more before u add ur smart ass comments
I said on a cold night u will hit 12 PSI.. on a humid day ur going hit 8-9 psi
and no u will not hit over 12 unless u have add ons
and it depends where u live at 2.... in texas its humid... so i hardly see my 15 psi on a stage 2 in lower WOT's i usually wont see my max PSI untill 6500-6800

So stfu
