I know that cruise is usually touted as giving better mileage, but not always true. I find that on larger hills, the cruise can be a bit slow to respond on many vehicles, which will rob you of efficiency. Also, what speeds are you driving? Fuel mileage goes down at higher speeds, the most efficient is not going to happen at 70 mph.
As far as Ford helping out with any aftermarket chip, not going to happen, and you also have to be careful as adding such things can void warranty. You could inquire if there have been any updates, but there may not be. As also mentioned, final gears in the axles can also affect what you get for actual mileage over what the sticker says is the rated mileage.

I have seen mileage change after 20,000 miles though. The Edge has improved, and I know I will likely catch a little over this, I have observed a slight increase with using synthetic vs conventional. Generally only good for 1-3 mpg though.
