Sounds like a mostly stock, untuned car for me. There are no tables that allow you to pull timing dependant on gear, so you are still just seeing an untuned pcm pulling timing because of heat. Unless you are looking at timing at the shifts, because torque management will pull timing at that point(you are ant that), but it should quickly come back up.

When I was tuning in 95° weather, even with proper fueling, I would start seeing knock if I did back to back runs.
