Fyi sport mode on an auto 3.73 bronco locks out 9th & 10th gear. This is actually lower gear ratio than 10th gear with 4.70 on sasquatch broncos. Mileage doesn't dive off as bad as people seem to think, I have been a solid 17-18mpg with both my broncos.
Mine drops off a mpg or 2 when doing 60+ in 10th gear. It's happiest in 8th at those speeds. Barely makes any boost unless going up a small hill.

Would you suggest Sport mode 100% of the time for 3.73's and 33's? I have an appointment with flip to get my speedometer calibrated on my Base, but right now my display with incorrect data says I'm averaging 17.5 MPG.

I think sport mode helps keep the boost down and the rpms up when driven appropriately.
