Ok I'm Either Buying A Stage 3 Or 4 Kit From Cobalt-addiction And Giving My Friend My Stage 2, Which Should I Get The Stage 3 Or 4, I Posted On This Before I Know Sorry, But I'm Buying One Or The Other Tonight Any Help?

 

you friend with the gm stage 2 kit won't be able to get the tune from gm...they won't give it out without an original number not already linked to a car. he can get a custom tune.


either way, go big...obviously you can't just stick with stage 2 so you might as well fullfill your need for speed.
