My buddy just bought a 2002 F250 Superduty with the 7.3 Turbodiesel, what is the best u[grade for one.

And do they really get 24mpg, I don't think I believe that

A buddy of mine has an 02 Excursion with the 7.3. He has a Super Chips programmer and he gets 25MPG.

an xcal2/3 and a bigger exhaust. Dont expect a lot better mileage, the trucks prior to 2008 MY dont seem to digest the ULSD as well.

What Obus said.. My tuners 2006 went from 15 to 21 with the tuner.

I put 4 inch, straight piped, turbo back exhaust. TS performance 6 Position chip. (run it on 75) and a napa 6637 air filter. My milage went from 13.5 to about 17 mpg's. This is a 2000 f-250 PSD crew cab 4X4 with service bed and lumber rack. (heavy truck)

guages,guages,guages!!!!!!before puttin a tuner,,which can change alot of parameters on a 7.3 It is highly recommended that the truck have EGT, Trans temp, and boost guages. In the diesel world,,,,the two most popular tuners would be Tony Wildman or contact DPtuner.com

being a former diesel owner, it should be in this order: 4" exhaust, new intake, gauges, then DP tuner. Don't really need the gauges until you start dumping extra fuel with a tuner, the intake/exhaust help cool down a stock truck's egt's pretty well.
