I've read all three of your comments.
You do realize that cars don't turn the alternator off right? You'd have to actually wire that up yourself. The alternator / battery is what also runs every electrical thing in the car (you realize there's a computer, and oh my, an ignition system that requires lots of juice).
Wind drag and weight are what predominately reduce mileage, you've made both of these worse with your modifications.
2-2.5% is not a significant enough change to make any claim, the wear on your tires will actually cause WAY more error than that as time goes on (more worn tires register more distance than reality).
It's much more likely that your numbers are just wrong, and that any change in your driving habits when you decided to start being "green" make up for any true change in mileage. Pull all that crap off your car and you'll probably do even better.
