There are a few good options to improve mileage a fair bit. There is a lot of stuff to read and most questions on the forum get answered really fast.

You will want to read about K&N intakes and a "TUNED" PCM. The exhaust on these trucks is very free flowing and has only enough restriction to make the VVT work properly.
