Original stock Pulling 40 foot Raptor Toy hauler to Tennesee I got 12 mph on highway running 65 mph. Not pulling trailer Igot 14.5 around town 18 highway. I install 50 hp tune I droped to 10 pulling trailer and 12.5 around town or highway. Like I have been saying when you first load any tune from predator gets great mileage I have had up to 19.5 highway then slowly deteriates. I am not going by on board computer I am doing the math on how many gallons I have burn verses distance.
