Default Octane Boost Worth It For Protune?

Hey i live in california and all we have here is 91 octane. Im planning on protunning my car next week and my questions are:

Does octane boost really work to make 93, is it worth it? If so, which brand is the best?
Will i notice a significant difference in power by protunning 93?
Is it safe to use for a semi-daily driver and are there any consequences?
Or should i just be safe and stick with CA 91 without octane boost?

My Car: 07 sti

Mods: Cobb V2, Headers, upipe, spt short ram intake, invidia catted downpipe, invidida race catback. walbro fuel pump, and ngk 1 step colder spark plugs.

Thanks in advance.
