1998 Expedition 5.4

Is it worth custom tuning? I don't tow anything ever. I'm mostly looking to get the best fuel efficiency possible (I don't really care about comments on how long it'll take to recoup the cost in gas mileage).

I'm in Appleton, WI. Is there anyone local that might be suggested or, anyone online that is highly recommended? Any preferred brands for what I'm looking to do? I've read a lot of posts on SCT, Superchips and Diablo but am not sure which would be the best for what I'm shooting for or if any of them would be good.

Thanks for any information. I appreciate it. Custom tuning stuff is sort of out of my comfort zone as far as knowledge goes.

Your best chance for fuel mileage gains (per your request, I'll skip "the don't mod for gas mileage speech") is SCT or Gryphon (re-badged Edge) with custom tunes from Power Hungry Performance, VMP Tuning, 5Star Tuning, or Troyer Performance.
