Performance and MPG's

I just bought a 2008 F250, 4x4. I had an 06 that I had put a 4" down pipe and 5" exhaust with an Airaid intake and Edge Platinum Juice with attitude. I got great power and decent fuel mileage. So far I love the 08, but the fuel mileage is way off of my 06 even with all the performance mods. What's the best way to squeeze a few more ponies out of the 08 as well as letting that sucker breath a little better and get better fuel mileage?
