i think the xcal's actually make a save of your factory settings before they install your tune and keep it on the tuner. not positive though, haven't bought mine yet.

Yes, they capture your stock tune first. Then, what you can do, is before taking the car in for service, reset the tune back to stock, then set it back to your custom tune when you get it back. I did that a few times when I took the car in for warranty service!
