Question about 100 octane

So i was thinking of running map 7 tomorrow and putting some 100 octane for a night at my local dragstrip. Has anyone done this? And also after i run out of 100 octane (only doing a gallon or two), can i safely run map 7 on 93 until i connect my laptop and switch it back?

Map 7: Race gas absolute target map. Peak boost 23psi. This is a fairly aggressive map and increases engine damage risk. Use with caution.

Your car needs to be fully bolt on ( downpipe, intercooler, charge pipe)
If you run out of octane, keep RPM under 2000 until you change maps which btw you could do using the steering wheel controls

Wouldn't recommend map7 on anything but 100 octane and like Mike said you have to be FBO!
23psi is very aggressive for N20/N26 so use with caution, cool night only at drag-strip for testing your 100 octane gallon you're trying to use.
Switch to other maps via bluetooth kit or steering wheel why risk it (bring your laptop in this case)

you need to adjust to new types of octane for about 400KM in order to achieve peak performance.
