Dumb question: are Canadian gallons the same size as US gallons?
If they are, then 16 mpg at 60 mph is lousy. My 2004 FX4 gets 18-20 at highway speeds easily. Two things to check are tire pressures, and your right foot. Those are the two most common causes of bad mileage.
I would expect winter mileage in snow country to be lower, too, especially if the miles driven are short trips where the engine spends more time warming up , than warmed up.

Whatever the person who programs it wants it to do.
The trans is electronically controlled. They can firm up shifts, change shift points, make it kick down easier, lock the torque converter at different points, etc etc etc.

so how would you set it to save a little fuel but still have good performance?

I never asked for a mileage tune, I don't care about gas mileage honestly. lol
It is all in the tuning though. Talk to a tuner and tell him what kind of tunes you want, and he'll tell you what he can do for you.
He may make you a performance tune, and an economy tune, running different octanes or whatever else you want.

Did a bit of a mileage test the other day on the Ranger. Travelled east to Winnipeg at 100 km/hr and west to Brandon at 90 km/hr. Ended up with 23.5 miles per US gallon. Not sure if I want to travel that slow all the time but at 90km the rpm dropped to 2000. Truck didn't seem to be sluggish on the one mole hill on the way home at that rpm.

The SOHC 4.0 makes significantly more power at high rpm than the OHV 4.0 but it does not need high revs to make power. The horsepower curve on the graph for the SOHC is at or above the OHV all the way from 1000 rpm to red line.
