worthwhile mpg improving modifications
i am interested in whether it is wise to buy a : cold air intake; new exhaust; computer program ; air intake spacer... i am particularly interested in actual results from other 5.4 owners. i plan to keep the truck for another 100,000 miles so every mpg improvement will help. i definitely plan to get a jack rabbit full metal bed cover and all terrains to replace my metric but about 33'' mt's. thanks.
i have an 08 5.4 4x4 with cai,tbs, custom single tube exhaust, and a bully dog. i run 91 octane performance tune and clear 20 to 22 mpg on the freeway and around 15-17 in the city. i have basically 33 in mudders and 20 in rims. also i just pulled a yaris from utah to san diego with the bed loaded with stuff (moved because im in the military) and got 17 average with all that weight.

Modding for mpgs is stupid.

Even if you took and halved the figure I put down for the efans + udp it would still take 25k miles or so to break even.

I agree, proper and regular maint. is the best way to maxamize your mpg's I did a cold air intake are larger throttle body both brand new and totaled $385.15 I currently get 21 mpg in city. I have added super coil packs and a stand alone ems will be on next week

What brand coil packs?
21 MPG's sounds incredible, I would like to know more about your truck. Like is it 2wd or single cab.
