In case anyone's interested, here are data logs from my past track weekend. For the first day, I had pulled about 1 to 1.4 degrees from base timing B from 6800 - 7450 RPM at 1.00+ g/rev.

As you can see, was getting a lot of FLKC above 6500 RPM and IAM dropped, so I started short shifting to keep IAM at 1.00. Overall I was down about 8 mph on the straight from my best lap the previous year (in cooler temps).
Before the second day, I changed the tune to pull 2.8 to 3.15 degrees from base B timing at the same rpms/loads.

Was still getting some FLKC above 6500 RPM and IAM dropped again, so I short-shifted. Picked up a few mph on the straight from day 1, but still down ~6 mph from last year.
I'm going to go back to my old tune for the next few track events and see how things fare.
