Solved the ECO MPG problem
I traded in my 2013 eco with a rear 3.31 for a 2014 eco with a rear 3.73 and I can't believe the difference in the MPG. I had come to this forum many times before thinking I was one of the lucky ones who didn't have a MPG problem with my eco. Now I come to it and I am one of those who are getting lower MPG.
The gears play and big part in the MPG and I have to wonder if its worse on an ECO compared to the 5.0
For the record I'm not complaining just wanted to note this observation.

gears always play a role. its a balance. too low a ratio and you will need to push the engine harder to accelerate. but generally yes, a lower ratio will yield better MPG while higher ratio will yield better torque multiplication for acceleration.... towing... simply turning the wheels. think of it as using a pulley system for a mechanical advantage.

Why would you trade a 2013 on a 2014?

I traded a supercab in on a supercrew. I saw about a 2 mpg drop in mixed everyday driving and a 3.5 on Highway miles.
The 3.31 and the 3.73 have no difference in acceleration, with all the torque the eco provides you don't notice a difference.

It does make sense though that 3.73's will turn lower MPG numbers. The 3.73 turns a little higher RPM on the highway, which may cause the Eco to kick the turbos in more frequently. Boost = fuel. I had an Ecoboost with 3.73's and now have a 5.0 with 3.55's. I have driven many 5.0's with 3.73's and there really isn't a huge difference except maybe a bit in the low end. With that said, my 2009 Silverado with the 4 speed trans and 4.10 gears averaged 18MPG on the highway.

You also gained some weight from scab to screw config.
