I'm still learning how to upload to DATAZAP though once I figure that out, I'll post a link to it for analysis, but I don't have access to 93 octane and can't afford the extra for the racing fuel (100 oct) that I have. Any ideas off hand?

On 91 octane you will see the iam drop slightly on occasions. It due to minor knock probably arround2000 to 3500 rpm.
You can pull a bit of timing out of the base timing B map.
few guys in california have done that try @
JB86'd he might be able to send you map or at least the changes to the timing table. or you can do it yourself if you read the knock correction links below
