I have been trying...problems are:
Finding a 03 car running a 4.6 with a 5R55s, only choices are the "New" T Bird and that is GOLD for those PCMs...like $600.00 up.
And the Lincoln Aviator, Damn it is a dressed up explorer with even worst MPG and as a SUV I bet has the same programing.
Next is the 05 up Mustang, which damn it like the 03 to 04 Ford Change the three PCM plug majorly.
Plus I am in PHX AZ and subject to smog testing and the PCM has to have the correct VIN number.
So I only can try to reprogram the PCM for the SUV, or try to figure out a interrupt like changing the O2 read outs, or the MAF IF it uses them to trigger the change or to compensate for the change.
Sadly that is only something I CAN do and it is not a fix for all the Fuel Injected trucks running a similar program, which I believe a lot of them do.
Like my 93 Chevy G20 Van which seems to get 14MPG no mater speed or up or down hills.

PS I cannot find any real world MPG pages, the
https://www.fuelly.com/ ONLY gives the over all avg. Not city and highway...
I ONLY consider Highway of any worth, city can contain and LOT of stop and go and a lot of idling so it can be all over the Map.
My testing show what my cars CAN do on a road trip.
I want the best MPG for road trips where I will out in the country miles from my local gas station and on long trips feel the cost per mile mostly.
Knowing MPG can help plan fuel stops and being able to shop for best prices.
I have found normally on the road the better prices are in big cities and a couple of miles off the freeways.
