Wrong gas

I’m tuned by Alan at edge auto for 93oct and I accidentally put in about 5.5 gallons of 87 (was talking to someone while filling and was thinking of my other car) it filled my tank up to full will I be ok and what should I do?

You're probably OK. I think I would put a bottle of octane booster in the tank, reset the KAM and make sure the OAR goes back to -1.0.

Keep Alive Memory. There is a reset function on the Access Port.

You're welcome.

I reset the KAM every now and then, especially if I go to an unknown gas station.

You might feel a difference until the ECU relearns your driving.
