Well I finally bought HP Tuners, I bought it because I am doing a v8 swap in my s10 but I figure I will play with the cobalt too. I've got a 07 2.2 auto with AEM intake and 2.4 intake manifold. I found stock tunes in the tune repository but nothing else. Does anyone have a compare file so I can get an idea of where to start.

 

Congrats bro. It comparing files on a car u have no idea about is a no no. I can help you if you'd like. Just let me know.
