Teh-Viking - I use the fuel sipping setting when up to speed and on the flats otherwise I am usually in the same setting as you. Without the the gear-vendor engaged, 315 BFGs KOs on wide rims, 3.73 limited slip, I am at about 70 as well. I don't have any clean numbers for mpg with this current configuration but freeway tanks were getting me 17mpg. That was with an old bullydog tuner, and no gearvendor engaged(I didn't know how it worked) loaded up to about 9500lbs and hauling ***. I have a road trip planned this month and can report back, hope to be closer to 19mpg now.
If you have not adjusted your speedo your numbers maybe better than you think.
Also, clean the filters in the fuel tank, seems to be a common reason for loss of mpg. There are a few YouTube videos on how to do it. You can also trim the vent tube back in the tank to gain a few extra gallons of capacity while in there.
I also did the air heater delete, fuel bowl plunger delete, went to a Napa air filter, cleaned the back pressure sensor and tube, and gained maybe 1 mpg. I had a 5.9 Cummins in my boat and was shocked at how many electronics are bolted to the 7.3 and spent a day undoing all I could. In retrospect it's probably a wash at best it actual gains.
Sorry, totally hijacked this thread with my 7.3 obsession.
