MPG gains?

I have a 2002 f-250 with 202,000k miles. There are no performance upgrades on it. I have searched and searched on this site but cant make up my mind on which direction to go on with upgrades. My number one goal is better mpg and dependable. Intake wise i think i have decided on a DIY. But i am wondering if its dependable. Then chip i really like what everyone has said about PHP, but havent found anything about the mpg gains with using this chip. And if I need to have gauges with a php chip. My goal is to get 500k out of this truck so i want it to last. But of course want some power. Thanks

do you have an auto or manual? I have a 2002 F350 Crew Cab 4x4 with a 6 speed, after doing the DIY intake I was getting 19.5 MPG driving it to work back and forth everyday and around town. This was driving sensible and not pounding on it but a couple of times. I just got an SCT multi switch chip installed by Dans Diesel Performance and put a 4" from the turbo back exhaust on, I will know by the end of the week if I have improved by MPG or not, I can't seem to keep my foot off the pedal right now, I love watching that smoke blow!

Get a TS chip and tunes from someone with a history of tuning a 7.3..TW, Bill, Bean etc.

MPG's will all support mods 1-3. No one can say for sure as every truck is different some will get 3 some 1mpg
