Will anything happen if I use 91octane gas instead of 92 octane?

I just installed my zex kit yesterday and I just realized that on the instructions it says to use 92 or higher octane gas to ensure safe operation of their kit. Where I live the highest octance gas is 91. If I am to use the 91 octane gas will it jack up my car when using nitrous?
