Been discussed at length. The short is yes, and yes. But it all depends on what you're trying to get covered under warranty.
A bad door switch is likely to be covered if you have a tuner, but a shot transmission if you have a tuner is an entirely different ordeal. Depends on the dealer and how hard they wish to look for the re-flash when you installed the tuner.
