Hey everyone. I wanted to talk to you guys about my 2003 Chevy Cavalier LS (2.2L Ecotec)that I have been working on making it's gas mileage better. Here is the list so far of what I have done:

New Spark Plugs
New Tires, Brakes, Struts
Spectre Air Filter
New Performance Battery
Turbo Muffler (welded)

Here are some photos to show you as well:

Now, my question is: Is there anything more I can do that would not only make it run better, but also make the MPG better as well? Currently it runs better than it ever has, but I am wondering if anyone out there has any tricks or hints that I haven't thought of yet.

Thanks for your time!
