Change the gears to 3.73 or 3.54 for better MPG.

red 96 that would be way to exspensive and plus its hard to find someone around here that is good with gear swaps. the few that have done it before i wouldnt trust them to fix it rite without having to go back to them time and time again. i feel that a programer would be my best bet according to all the post i have read on this website. i wonder if going to 20" wheels would help.

Going with bigger wheels will hurt your fuel mileage a bit won't it? I know when i went from my 18 to 20" wheels and different tires it certaintly did not help my mileage  
2005 2500 dodge ram banks 6 gun w/speed loader,turbo back stright pipe, S&B intake on its way, phantom gauges,20" gear wheels with Cooper Xenon tires,and much more to come
