If your looking for MPG increase similar mods to what you had before are best. K&N, a nice exhaust setup, maybe even an intake. Nelson computer tune can also give you better mpg as well as more power. With all of that listed above on my truck I can see 15 on teh highway lifted with 35s and stock gears, so I can almost promise you will see better than that. Headers also would help I would guess. Its all a matter of how much you want to pay for a but of a MPG increase.
