Hey hhcobra, make any progress?

Have you made any progress towards higher mileage on the big Ex? I have the same... 01 7.3L 4X4. Am interested in learning if you've made any progress. I'd love to see 25 highway if poss. Have been able to see 22.5 display average on a 700 mi trip... but would LOVE to learn any insights you might have since your quest began.
