With only the mods in my signature I can get 22mpg on the highway at 60mph

I would look into the PPE standard or PPE econ, depending on what your future plans are

There are many different choices out there, you can even buy pre-tuned ECM's that you basically unbolt your stock one and replace it with a tuned unit, you can even get switchable tunes that allow you to run 5 different calibrations, I currently am able to run a modified stock tune, a 330rwhp tow tune with turbine brake, 365rwhp tow tune with turbine brake, 370rwhp all around tune, 415rwhp race tune, and they are all transmission safe, well except the 415 if you beat on it hard
