Default MPG's Improve or Accept??

Alright I have had my hemi now for about a month and I knew it was going to be a thirsty truck but I'm hoping to squeeze a little more out of it. I have gotten as good as 14 and as low as 12...(well except for that first tank but that was the "test the limits tank"). I drive very carefully as to get good MPG I coast as much as possible, I take off slow, I try to bait traffic lights so I don't have to stop. The 14 tank had a lot of highway at 60-65 as I try to stay under 70mph.

The truck is 2003 single cab with 93000 on it I changed to full syn motor oil wen I got it cleaned the air filter and ran STP in gas. Tires have good press. I addressed this issue in another thread but the muffler was changed to a flowmaster 40 series by me after the previous owner had a single chamber with no pipe on there and had the computer reflashed with a "P2106" and "P2175" TSB PCM.

So is there room for improvement or is this the best I'll see. Any advice is appreciated.
