Your best 60' and mph are good for mid 11's for sure! It's always a successful day when it is in one piece after a day at the track.

Is it fuel injected or carbureted? It almost looks like fuel starvation as the mph is very close at the 8th and then drops off pretty quickly in the back half. I assume fuel injected based on the datalog comment- would be interesting to see if timing was the same for all runs, and what a/f was doing.
