Bang for the Buck
I have a 2000 Expedition 5.4 and was wondering what you guys think are the best mods for the money. I am mostly doing them for gas mileage and horespower. What does anybody suggest to do for the biggest improvement. Any extra info would be appreciated.
My current mods are a True Flow intake, Hypertech Max Energy tuner, custom exhaust, E3 spark plugs and switched all the fluids to synthetics. I also went over the vehicle with all the regular maintenance jobs, fuel filter, all the goodies etc.

That was not my point, I just wanted to improve the gas mileage. I know my truck is not fast and I'm not trying to make it fast just improve the overall performance and gas mileage.

ROFLMAO!!!
Have the girlfriend drive you around.
Seriously, the only way to make a signifigant difference is to drive by your tachometer. Keep it under 2000 RPM, take off slow, coast to a red light/traffic/stop sign, etc. If you do much interstate driving then drafting a big rig can be done with dramatic increase in gas mileage. Properly done you will never have to get too close to the rig. I have seen a 40% increase in my mileage drafting from a safe distance.
Naturally a clean air filter, stiffer tires run at their maximum pressure, a good alignment(get the lifetime alignment at the same place you have your lifetime rotate & balance & get it done regularly). I get rotate & bal. with every oil change and alignment every other one.

With your more efficient driving habits what type of mileage (mpg) do you get?
ROFLMAO!!!

Explain the custom exhaust a bit more.... that may end up hurting more than helping depending on the size, length, and scavenging result of it. Also, ditch the Hypertech as a generic tune is doing you no good at this point. The plan would be to do all the mods (especially involving air and fuel delivery/exhaust) then get a real tune on a dyno to maximize the benefit from all the mods collectively.
The other enemy is weight. Ditch as much weight on the truck as you possibly can.... i.e. third-row, smaller tires (assuming they are larger than stock), sound system if you got it, and if you want to get extreme ditch the spare tire, swap the hood with fiberglass/carbon fiber, aluminum driveshaft, etc etc.
Other than that, just know that more power doesn't normally coincide with better mpg, but the biggest enemy is weight and aerodynamics... both which aren't an easy fix.
