Just got an xcal2 from Wayne, and was wondering if I can bounce between any tunes that are available or do I have to return it to stock before I can upload a new custom tune.

You can bounce between tunes (or even reload the current tune if you need to) without any problems...just remember that your ECU needs to relearn everything after you flash it, so it's best to give it a day or 2 to calm down a bit
