Well for my take on MPG by the vehicle manufacturers,Most are tested in a lab under controlled conditions,with the very best lawyers taking all the info and adding their style to the "definition what "is" is".All manufacturers are in fact the best liars for mpg ratings,and trying to prove that they are wrong, it"s easier to prove the world is flat.Now with that being said,take 2 vehicles,being same gears,transmissions,but put in two different drivers, gauranteed you"ll get two different mpg ratings.For the most part even with 3.73 gears,you can change tire size,to get down to 3.55 gear ratio,but the trade off is having to get the transmission recalibrated,and if ever you change back to original size tires, have to recalibrate the tranny again,unless you buy a aftermarket controller for it and every time you change tire sizes,you can change the tranny codes.All require xtra cost,but more flexibility.Some of the aftermarket controllers let you adjust the performance to your needs,but only to a certain extent.So with that in mind, I would say you would gain maybe 1-2 mpg difference between the two ratio"s,but just my opinion,not factually tested and proved.LOL LOU
