Hate to say this, (prolly raise some flack) but Ford has huge teams that do NOTHING but optimize their products for mileage. It is one of their primary goals. They have computer models, trillions of bits of test data, wind tunnels, performance testing, etc etc. And a bit of know how. In other words, there is VERY little you can do further the very high goal that they have already set for themselves for ANY vehicle they make.
Putting on a less restrictive exhaust, as has been pointed out, may in fact make things worse. If you make the pipe bigger, you slow down velocity, and can seriously alter the scavenging dynamics that may have been designed into the total system.
The Gotts mod (or ANY CAI for that matter) is also a very dubious mod if mileage is your goal. The restriction for any mileage consideration is in the throttle body, as it will only be open to about 25% or so during cruise. Having a "better intake" means very little when your pumping losses are right there at the throttle. (One more reason why diesels can be more efficient)
Anything that can increase mileage is really a compromise. For example, you can pump the snot out of the tires to their max pressure rating. You would give up handling, and gain some weird and premature wear. You would lower the overall rolling resistance, but at what cost?
As stated earlier, we are driving a 3 ton brick wall. The very best mod would be taking the ball bearing out of your ankle and the lead weight off your toes. The sweet spot is somewhere around 45 or 50 mph. Certainly anything over 65 will raise your spot on the graph in a very non-linear manner.
My last fill up was 11mpg, winter is killing me.
