The benefits of being able to flip the chip on the fly, didn't outweigh the options of the Xcal2, and I know that I can drive around on my nitrous tune all day, and spray when I want. It's no big deal to pull over, shut the car off, and switch my program to nitrous, if that's what I want to do. I usually know when I'm going to need the juice.

True, and you still have to shut the car off to flip the tune on the chip IIRC. I think it will screw [censored] up if you flip it in the middle of accessing data.
Like I was saying earlier, the stock code is more than able to pull timing in the event that low octane fuel is used.
So except for a nitrous tune or a serious high boost engine like 14psi+ tunes on 10:1 motor, I can't see the need for a second tune.
