EDIT: It's actually a 2007
Can someone tell me how much can be gained with tuning one of these? 2007 Cobalt SS 2.4 Auto, stock with a cold air intake. I've been watching The Tuning Schools GenIII/Gen IV videos and it seems a lot applies to these also. I think I unnderstand the torque management tables changes but I'm mostly wondering if any gains can be had with timing adjustements and what to change in the trans.
Thanks
