what mod first?
I own a stock 2002 7.3 crewcab. I also have a hard tannau cover over the bed. Currently i get 21-22 mpg on highway in summer. (18-19 winter) I have manually run the #'s and they are correct. So whats the verdict on doing any mods, should i mess with it? im not sure if i can get any better or not. I;m sure i can get more power with a mpg loss. So now my question is should i do the air first and what impacts would it have, then exhaust then chip or just a tuner and see what happens, I dont have a egt guage either to monitor anything so i wanted to put the pilar in also. Or should i be happy with the mpg i get now ... any ideas? I also saw in[font=verdana, geneva, lucida, 'lucida grande', arial, helvetica, sans-serif][font=verdana, geneva, lucida, 'lucida grande', arial, helvetica, sans-serif]diesel [/font][font=verdana, geneva, lucida, 'lucida grande', arial, helvetica, sans-serif]power[/font][/font] some "kits" that include the tuner air and exhust for one price.

The fews thing that gas, and oil burners have in common are simple principles for making power. Getting air in, and getting air out. The more (air) you can get in, the more fuel, (gas) you can add, more power is the result, if you can get all of the spent gases out. You will find little or no adverse effect on fuel (gas) mileage. Might even help. Do invest in some quality gauges, so you can see what's goin on. Consider a trans temp gauge as well. If you are going to start makin more power with a tuner, you are undoubtedly gonna have some fun with it. So as you are smashing the skinny pedal, you will want to monitor that trans, so you dont burn it up too.

Definately
1 Let it breath - Intake & Exhaust (Turbo mods and increased boost i would put off till after #3
2 Monitor it - Pyro, Boost, Trans Temp gauges
3 Fix weak points - Transmission
4 Choose Tuner - DP-tuner (Dont think you will find a better powerstroke tuner out there)

Ditto to all. Unfortunately while these mods can result in increased fuel economy, my mods seem to have come with lead boots. I can't seem to keep my foot out of it. I gladly trade off the economy for the performance. Any reduction in mpg is purely my own fault by choice.

Gages first especially EGT. Most mods will raise the Exhaust Gas Temps....very dangerous to the turbo. 1200 degrees is about max you want to see. A little higher for short bursts.
BTW: Mount the EGT probe before the turbo.

I would get gauges first. Not as sexy but definately necessary. That way you have a baseline of how the truck operates instead of not knowing if this value is too high, too low or just right.

the turbine wheel is made of a special metal blend of Tungsten and Inconel which can withstand 1800+*. however your turbo will be taken out long before that temp, as pieces of the piston and cylinder head begin to melt and hit the turbine wheel.
