Yhis may sound strsnge but my boost guage reads way higher than it should. Iknowe they should be getting around 12.5 psi, but at redline mine reads 17.5,I only have an injen intake. Have any of you had any guage malfunctioning problems?

 

Uh oh..

 

Somebody else was having this problem.. Unfortunately it led to his many malfunctions haha.

 

mine runs toiaround 80 KPA. don't know what that converts to in P.S.I. tho, and i'm too tired and lazy to find out right now.

 

80ish is around 12psi

 

sounds like your cats messed up man..... im running 15psi with boost bypass and a 3 inch pully

 

cool... ya thats about right then. I had seen others with gauges around that also, but they were asking if that was normal too so i wasn't completely sure... thanks.

 

yeah...something is definitley messed up.....I'm running just shy of 17psi, with intake, 2.9, and boost bypass mod.

 

go out and get urself a new cat

 

stock pulley i'm fine around 12 - 13 tho ... 80 - 85 KPA ...

 

stock with under 1000km on the car 90 kpa

 

I ran 12.5psi stock and am at 16psi with GM stage 2.
If your pushing that much boost stock then ether your catt is on its way out or that gauge is broken.
Get in and have the dealer check it out ASAP! But take the intake off and go back to stock first so they dont give you crap about it.

Later

 

I guess i'll drop it off at the dealer and see what they say.

 

Did i mention my car only has 880 miles on it. Is it possible for the cat to go out that fast. And what could the consequences be if I don't get it fixed soon?

 

intense stage 3, 18 lbs.

 

19psi

 

yeah... thats not right man. 16psi on a stock engine with low milage..... get that to the dealer.

i kno i only run 10.5-11 (11 if im lucky), but that is because i am at high altitude. the altitude is only making a negative 1 to 1.5lb difference tho. so running nearly 4psi higher doesnt sound good.

or maybe you have a super super sport cobalt =P

 

definately sounds like you have a clogged cat

 

115kpa
