2001 7.3 regearing help! Bad fuel economy!

[Jayleeberg]

I have a 2001 7.3 supercab short bed with a 8" lift, 37x12.5x22r's wheels, Edge chip (on economy mode) intake and four inch turbo back, and get at best 12.7 MPG. I need to know if regearing this thing will help with my **** fuel milage. Has anyone HAD EXPERIANCE regearing a similar ford, and gotten better fuel milage. I have heard everyone opinion, but need to know for a fact if regearing will make my MPG better. THANKS FOR HELPING ME OUT. (ps im not worried aout the price of regearing.)

I tend to average about 12.3MPG or so myself. I have a 6 pos bully dog set on to the enconomy mode as well. I know my milage is lousy because i don't get on the freeway much so my milage is down because of that. Maybe driving tendancies could be a factor as well. I think about 45-55 seems to be the sweet spot for optimum MPG. Anything above or below is going to affect MPG as well. When on the freeway if I go above about 66mph and my RPMs are at about 2000RPM, then I really notice the drop in fuel economy. I also have stock size tires as well and running swampers will also kill your fuel economy.

Do you know anyone who has regeared back to stock and improved fuel milage though?

[Stroker9883]

No, I don't know for sure. I haven't read anything on this site even mentioning it in the last few weeks.

Going to a 4.30 gear with that size tire would help quite a bit IMO
