Race Chip Ultimate questions.

I bought the race chip ultimate for my 2013 550xi and absolutely love it. However, it is time to take the car to the dealership for routine service, so I need to remove it. Here are my questions.

1. Can I just unplug it or do I need to use the bypass plug first?
2. The setting is currently set on "C". Do I need to lower to "B" for awhile before removal?
3. When I reinstall the chip, can I install it on the "C" setting or do I need to start at "B" and work my way up again?

Last question, what is the highest setting that you have used?

Thank you.
