    04 sunfire help tuning cold air/ 4-2-1 header

    I have an automatic 2004 2.2l ecotec sunfire. I am looking to make the engine more efficient . I want to gain some more power but I also heard while doing this you can also gain mpg(if you keep your foot out of it). I have a starting point but I don't know what all I should do. I was looking to lean out the car at my crusing speeds (75-80mph). Any help on engine/tranny would be great! I attached my stock file and my modded file. Thanks guys.

    I changed a little more stuff. If anyone can check it out and see what all I would need to change for a baseline before I go out and try and drive and tune. Thanks
