I would agree Tony that it feels geared too low. It has a 2.88 gear ratio and 195/70x14 tires. Top gear is 1:1 with a torque converter that slips a couple hundred rpm.

Somehow I don't see me blocking off two diesel cylinders.

Help me understanding the graph, what does the dashed line sloped up to the right and the solid line at the top mean. The graph is for the heavier SD rather than my D Does that make a difference?

Looks like its overpowered or geared too low for maximum mpg. Deactivating 2 injectors would put it at 37 mpg.
