An obliging tech could tell the truck it had smaller tires and increase the top speed.

Factory 20's are 634 rpm per mile. You could change that to say 700 rpm and that would raise top speed to 116 mph. You would have to live with a truck that goes 10 faster than the speedo shows though. It would also make the odometer read low.
