In general, always return back to stock. Nothing sucks worse than finding out the hard way that your dealership reflashed the PCM while your programmer was still in a level.
It doesn't matter that you're going in for window repair or a flat tire or whatever. If the dealer can make 1.0 hours doing a reflash (even under a TSB or warranty) they are going to do it so they can get paid on it. Not worth the risk in my book.
Plus like banks said, many dealerships will try to crucify you if they find out you've modded your truck. Doesn't matter that the programmer has nothing to do with the issue at hand, they're looking for any excuse to make you pay. Don't give them one.
