7 or 8 data points throughout 2 gears doesn't say much. But WhiteTsiAwd is correct, you need to go richer to get rid of that knock.
First, you need to try and get more out of that logger. Are you running the Pocketlogger program?
What are your Hi SAFC settings?
After fixing the logger and adding fuel, make a pull in 3rd gear from about 2.5k to redline logging rpm, timing, knock and airflow and post that up.
