Title says it all, this is assuming that I keep my temps in check. I just like the way the truck drives in that tunes even when I am not flogging it.
Thanks.

I'm not a diesel guy but I'm sure that would be fine. The many of the gryphon users (both diesel and gas) drive in their performance tunes all the time. With a careful pedal you might even get better mileage, but it'll probably still be pretty close to your 80 DD tune.

DO IT, BOB!!!
It's not going to hurt a thing.
If you like the way it drives in 100 Perf. then enjoy it!
