Luck has nothing to do with it. Making sure all systems were operating as designed had everything to do with it.Building a fairly stock motor designed to work within stock Ford program functions insured a great running combo.in your particular situation, you may have had it nailed, or tuning may have netted a few more mpg at steady hi-way cruise. i have never seen tuning not net gains in one area or another, but i have seen it where the gains were not justifiable against the cost of the tuning. i know if i was getting 18 mpg with 35 in tires at 65-70 mph i sure as fawk would not change a thing and be glad i got that damn lucky.
At 6mpg there is obviously something amiss in his setup.Chances are good its something very simple like a TPS reading out of range,an O2 sensor not feeding back correctly or at all,timing to retarded or a bad ECT sensor. All basic things that paying for a dyno tune would render useless. Im just suggesting before he pays for a dyno tune he spends an afternoon checking all the basics {because most dyno shops wont} and making sure everything is operating 100% correctly before dropping $300-400 on a shop tune to only end up where it should have been to begin with. I would guess at least double the MPG is possible in his Ranger with current parts.
