Looks like you may have had a misfire around rows 15 through 20. Timing was pulled, requested boost was pulled back, and AFR was momentarily pretty high.

You could check your plugs and gap, otherwise is probably just low octane. I would take some more logs on map 1 and see if the behavior continues or is consistent, and if so see if there might be a way to tune around it ... or move out of California so you can get decent gas.
