I have a 2006 cobalt ss with a stage 2 kit from ZZP. It have a 3.1 pulley, 42 pound injectors, stage colder spark plugs, and a tune from them. Out of now where the other day I went to get on it and the boost gauge jumped to 20 psi and the car bogged down and basically lost all power until I let out. I can hardly drive the car because it doesn't have any power once it starts to boost. The supercharger sounds terrible and it give off a weird smell. It is also burning more fuel and gets a little warm when it tries to boost when it is under a load like trying to get up hills... I really need some help since this car is daily driven.. Anything would be greatly appreciated..
Thank you for your time!

 

Cats fried.....

 

I had a similar problem and my resonator was plugged. Could be the catalytic converter as well.
Does it lose all power above like 3-4k rpms?

 

It loses power any time it tries to build boost.. The supercharger sounds really weird..

 

gut the cat

 

Yup sounds like its time to replaced the cat or delete it.

 

Yeah same thing happened to mine. but it was the resonator for me. so check them both out.

 

Cat

My blower sounded like a slidewhistle and made zero power

 

Yeah it did end up bein the cat. Thanks a lot guys!
