I purchased a 2016 Expedition & overall I'm very pleased. It'll avg between 20-21 mpg on the highway but falls to 17-18 around town. I've had good luck in the past with tuners/programmers increasing mpg, I'm not looking to gain big hp I just want to see better fuel economy. I've been looking at TS Performance EcoPro Module, which plugs into 2 sensors under the hood & doesn't leave a footprint. Does anyone have any input on this or any other tuning for better mpg's?
Thanks
