Best fuel economy tuner for 04 ram 1500 5.7 hemi

[alextuynman]

I just bought an 04 ram 1500 hemi. I drive about 6 miles a day with it. As work is about 2.5 miles away.
I'm getting about 10.5 mpg at the moment. Granted it is winter here and I allow my truck to warm for 15 minutes before I drive away.

Is there any tuner that will allow me to get better mileage?
Thanks for your help.

had the same truck before my '14 2500 and I had a predator tuner on it, with just the 87 octane tune and I would get ~ 13.5 mpg around my house...I had some bigger tires on it but that is about the best I could get. I think I was getting like 12.5 without the tuner, so not much difference. All of this is according to the computer on the truck not my calculations, so take it for what its worth.
