...well you might be mindful of needless accelerations....so the guy behind you gets a little testy...big deal...you don't have to impress anyone with your rapid acceleration...if not haulin' take the economy car instead~

The obvious is a ring & pinion / smaller rear end gear ratio but acceleration will suffer but top end & mpg will improve. Example like a 4:10 ratio changed to a 3:23, bigger dia. tires pumped up hard ,for less rolling resistance, smaller mm fuel injectors? a flush hard bed cover for better air flow, that bed catches too much air & drag, & look into finding & buying a "Hone-O-Drive" unit that mounts to the rear housing, people have been successful with these on RV's & Hummer's (if you can find one) it adds an overdrive gear up to your final drive.

best way to get better fuel milage put a cold air intake on and a good cat back system it does help and gives you some more power
