20+ mpg with Kennedy economy tune

[Mark Rinker]

I have read for years on TDP about 20mpg trucks, but rarely been out of the mid-teens myself.

This last weekend I drove a 400 mile roundtrip to deer camp, loaded with gear, but no trailer. A rarity! Got 20.2mpg for the trip, and that included a few stretches with cruise set at 76mph, some full throttle blasts on the haul/ass setting, and 6 miles of muddy wooded roads!

I think the truck would do 24 if you drove 400 miles under 65mph with no heavy foot.

Amazing - especially for 170K miles on the odometer!!! The fresh set of injectors certainly helps.
