Good points. I don't have OhCrapStar activated on either the truck or the 2010 so I don't care.
I have left my Range in the GMC for over a week at a time without starting and no issues. Starts right up. But the battery drain potential is another watch out I've heard about. But it's easy to do to unplug it.
Again, the right way to do it is get a tune, but sometimes you want to keep your warranty intact without rolling the dice.
