I have a stock 06 cobalt ss/sc but I boost 13-14 psi, is that normal? Or do you think the old owner did somthing to it?

 

Sounds about stock to me... with our altitude around here...

edit: at least thats what I get from reading the treads around here but someone with an ss im sure will post to conferm...

edit: 12psi is stock boost

btw google is your friend...

 

Is the supercharger pulley bolted on ? If it's stock there wont be any bolt's ... they are pressed on from the factory. It could be the gauge is off a little or the cat is starting to get plugged up some . What is the rev limiter set at? 6500 is stock 7000 is staged.

I jus found out my car is a stage 1!lol

 

stage 1 doesnt raise boost. stage 2 does

 

This.

Stage 1 is just injectors and a tune. Changing your pulley size changes boost.

I'd say it's normal. And don't trust the stock gauge. It's not exactly the most accurate.
