Ya, I swapped the gears out when I lifted my truck. My speedometer is off, so I'm not exactly sure on my fuel mileage. Before the lift, I had 3.08 gears with 31's and I seem to use the same amount of gas each week with the new gears and tires. I've currently got a 305 in the truck and I like my gear selection. Like I said in my other post, you really need to decide which transmission you want to run before you decide to regear it.
