Any help here would be great.

I am looking for the best way to get better gas mileage. I have a 2door, automatic trans, 4inch lift, 33 inch tires, Cool air intake, Throttle body spacer and exhaust.

What would be the best tune to use with my Superchips Flahspaq?

Any Ideas? feel free to PM this is my daily driver and mountain toy. right now getting about 13 miles per gallon.

thanks everyone
