Default 93 stage 2 map with 91 octane

so ive searched this question with no luck.. i just moved to socal for mass. out in mass we have 93 octane so i was running a stage 2 xpt 93 octane map. driving across the country i found that iowa and nebraska only have 89 octane and 90 octane was a treat. now that i live in cali i can only find 91 octane. am i doing harm to my car by using the lower octane, and should i try to flash my ecu to a 91 map? i currently don't have a laptop like back east. so its a bit more of a hassle to do.
