My tune is DMS. There's no reason for my family vehicle to run like a striped ape all the time. (For my wife when she's out running errands/groceries?)
There is also no good reason to not have "Sport" run like a striped ape, when it is possible.
Also, there is an "Eco" mode, why not let it baby-drive a little? Towing?
This thing is going to be in a snowy region, being able to keep your thumb on it is a good thing.
ps, I got my rev 1 last night too late to flash, so I'll be out there tonight doing all the data logs!
