Any one know of a good combination of a programmer, intake, and exhaust combo that works well w/ an '06 6.0L FX4? I'm looking for the combo that will get me the most mpg possible. I'm running 325/60R18's w/ 3.73 gears now and am seeing about14-15 city and 17-18 highway. Not heavy footed either. No towing. Reply to post or PM me. Thanks.

 

I like the edge evolution or edge juice. I dont know cause ive never owned a 6.0. i have a few 7.3s and have got 22mpg with 3:73 and 315 tires.
