The mpg vs. speed link is incredibly pertinent. You have it in your head that the problem is "A" when the problem is actually "B". "B" is the laws of physics - where more speed creates more drag and more fuel burn and more rpm moves more air through the engine that requires more fuel to burn at the proper stoichiometric ratio regardless of what you trick the ECU into believing.
Here's the EPA rating for your car:

41mpg highway.
You're not going to get much better than that especially at 70mph+
Here's a little reality check:
2008 Prius:
1.5L motor
2900#
At 75mph, I get 40-45 mpg.
2012 Ford Fusion Hybrid:
2.5L motor
3700#
Gas engine is 67% larger.
Car weighs 800# more.
But you think you should be able to beat a Prius (lighter and more aerodynamic) by spoofing the rpm?
