What can be done to a 7.3 to improve fuel mileage before fuel prices increase again? 2000 F350 dually, 6SP, 140K. This year new PCM, 2 new CPS, 1 new 3rd inj., Bully Dog 2 years. Thanks
What are you getting now? You can get better tunes that will help. Not the Bully Dog, but custom tunes, DP-TUNER. The 7.3 is an incredible engine, you just need to know how to massage it.
Check for boost leaks as suggested by Chris is Post #9 of your other thread.
Also check that you don't have a clogged tube going to the EBPS. This is the link for cleaning the tube but it doesn't seem to be working right now. http://guzzle.rbmicro.com/epbs.html
All of the above, plus keep your foot out of the pedal.. Keep you tac around 1900..
My dually doesn't get very good mpg either.. empty about 15.. pulling a 6000 lb load, about 11..

Yup. Actually on hwy 1900 is about 65MPH. Set cruise. Locally I shift sooner and run around 14 - 1600 RPM. I will eventually get 4 inch exhaust. Thanks!!!

With my 7.3 F-250, Crew with Hyper-tech tuner in stage 3, standard tires and 3.73 rear, I get 19-21 empty on the road and 12-13 towing my 30 ft, 11,000 pound, 12.5 ft high 5th wheel as long as I stay around 17-1800 running 65 MPH. But if I kick it to 2000 rpm I turn 70 but mileage goes to 17-18 empty an 11-12 loaded.
