Hey i was wondering. Will you pass emissions with stage 2 comp cams? I know a few people on here have put cams in but can you pass emissions? Mine should be here next week and i'm putting them in either way, i was just wondering though. Also with stage 2 is there any overlap? I think that will determine alot of it.

 

As long as you have no check engine light or monitors that are not ready you will pass regardless of what cams you have.

Fails involve a CEL related to any part of the emission system, and since these cars are ODBII and not the stick up the tailpipe, you don't have to worry.

OR

Fails involving monitor's not being ready because you reset your computer too recently

 

I've asked this question a few times before and was told that stage 1 is Ok because it will run without a tune and not throw any C.E.L.
Does anyone know the stock cam profile on the 2.2 cobalts?
Compare and see how much more aggresive grind your stage 2 is compared to the stock one

 

Run a stage 1 comp cams setup. Stage 2 gets pretty aggressive for the street....

 

no i already ordered stage 2. I'm actually waiting for them right now.

 

Yeah...here you go
