Best gas upgrades?

What is the biggest bag for the buck? Tuner? Electric fans? Underdrive pulleys?

Looking for MPG improvement and some power improvement.

keep your big foot off the go pedal. try and stay at or below the 2000 rpm mark. oops, i just saw that its a 5.4, not the v10. well, in that case, sorry, i dont know..

i would say electric fans, only because i dont have them. ive bought the k&n kit, 250, a tuner, 300, and havent gotten 1mpg better. regear the differential would be the best bang for buck. wont change the mpg much and power addition will be night and day! good luck!

What tuner you using? What kind of mpg you getting?

Don't think I want to go higher than 3.73 gear.
