My friend just bought an 06 4x4 crew cab dually with 4.10 axles. I picked it up in Texas and am driving it back home for him. From what I've seen, it gets from 12-15 in town depending on how you drive it and how much idling, and it gets from mid 15s to high 17s on the road. At 80-85, it gets 15s. At 60-65 it gets in the 17s.
That is all bone stock. His programmer just came in today, so I'll know what it gets with the Sct as soon as I start my trip home.
The mileage was far worse when I first picked the truck up, but I changed the oil and went to synthetic, and I changed the fuel filters. You might try that.
Your engine warranty has a lot left on it. Powerstrokes all have a 5/100 warranty on the motor. As far as running without gauges, it's not a good idea. If you must, only run the economy tunes, and don't beat on the truck. In DJ's eco tune, I never see more than high 1100 EGTs, but I have a 4" turbo back exhaust. I bet they'd be higher with stock exhaust. You can probably get away with the stock exhaust on the low power tunes, but I'd definitely get a pyro gauge at the minimum.
