JB4 meth injection question

Today I ordered the N20 BM meth kit with stealth tank and will be installing soon. Also going on will be an Injen CAI, Wagner catless downpipe, BM replacement intercooler and 2 step colder plugs.

I had searched around and didnt see this clearly answered anywhere and it may be silly to even ask, but is it fine to switch between other tunes while meth is hooked up?

For example if I want to just run stage 1 for a while or if my girlfriend will be driving the car and dont need it running the higher boost levels. I understand meth will not be activated but just want to be sure this wont cause anything wonky with the car, or the tuner.

I'm assuming that Map 1 won't be programmed for meth so it won't be spraying on that map. If that is the case, which I'm not 100% sure of but I think it is, then yes, you'll be fine and can switch maps.
