Its good to know the correct ratio, thanks.
You dont happen to know what RPM is the sweet spot for fuel mileage for a 7.3 is? 2000 rpm has been suggested. If thats the real rpm goal at a cruise speed of 60 mph, my 225/75 tires have me damn close.
So why do i get 10 mpg???

2002 E-450 Cube Van 80K miles, regularly serviced.
I bought the van used about 2 years ago for my business. I am the only driver.
I had a F-350 PSD prior to the E-450. The F-350 always got 14 mpg or so, I figured the E-450 would gett at least 12 mpg, it never has.
Van is operated carrying around 1500 pounds of equipment at most times. Occasionally I go to jobs with my water tanks full which adds 4000 pounds (500 gallons)
Oddly enough the mileage only drops about 1/2 mpg carrying a full load of water.
The best mileage I ever got was 11.1 mpg after driving at 50 mph or below, babying the throttle, carrying minumum wieght. So the MPG spread is 10 to 11.1.
I agree, something aint right.
The van runs fine, typical bad glow plug cold start issues, HPOP oil lines leak (I just ordered parts to fix both of these problems)
Tires/engine RPMs is about all I can think of.
Ideas? Man I would love some advice that would fix this van.

Well, it sounds to me like its running rich. While I don't know alot about the 02 diesels specifically, injector pump timing or maybe a boost leak would be my first throughts.
