Please help quickly?!

I am going on a road trip tomorrow and my charger is currently tuned to 93 octane. My problem is, I do not know if I will come across enough gas stations that sell 93, so my best bet is to tune it back down to 91. So, do I need to do a factory reset first, or can I just choose the 91 tune?

I'd prefer to keep it at 93, but it looks like there are no real good octane booster options that are even remotely affordable.

If I could get an answer real quick, I would greatly appreciate it!

Just load the 91 tune no need to go back to stock load and go.
