turbocharged big block MPG reports please

now that the number and quality of turbo installs is rising on this board, a relevant question arises.
in the application, all sorted and dialed, are there any relI able reports of fuel mileage?
especially in trucks.
especially, especially, in heavy trucks?
thx

Hopefully a few owners of turbocharged setups will chime in....

I get 12mpg in town and around 20 highway. I'm sure I could do better around town but I play around too much. I just love the noise my truck makes. It weighs 4760lbs

I get 15 normally in stop and go traffic and ive gotten as high as 17.5 mpg on highway on a 160 mile trip at 65mph. This truck has a tonneau cover and 65mph is just over 2k rpm. Think it weighs 5k

those are respectable numbers.
comparable to N/A engines.
but with a ton more power I imagine.
let's assume reliability is equal between turbo and non, the only greatly enhanced cost is rear tires!!!
