I tow my 27', 6500lb, boat with my ID street tune frequently. The only time I have to watch my exhaust temps is when i'm leaving the marina and climbing the very steep 1/2 mile stretch of road. Even then I can accelerate up the whole climb without breaking 1000deg.
On longer trips, like to Tahoe, I will reprogram to my tow tune. This way I don't have to watch the exhaust temps as much on the long steep grades and I benefit from the turbo braking on the down hills.
As far as milage, I couldn't say. I have no real set driving pattern to give a good baseline and i've got my foot IN IT every chance I get.
I do know that if I can keep it under 2 grand cruising that it will get substantially better milage with whatever tune i'm running.
