I'm stuck with an automatic vehicle, too. That said, my MPG went from about 28.5 pre-ecomodder to 33 presently (average since joining). (I'd like to get that higher, but winter is bogging me down.)

Reiterating others tips, consider a scangauge and an upper grill block. The scangauge helped me learn the 'sweet spots,' which happened to be between 35-65 mph. This is also the range in which my DFCO (Direct Fuel Cutoff) functions. VERY good for mileage. Good luck.
