Your log is difficult to read, please make a short log. Use manual transmission mode and get in 3rd gear at 3000RPM. Start logging. Floor pedal to 100%. Shift into 4th at 6500. Run 4th up to 7100 and then lift pedal. Stop logging.

This two-gear pull will give a good picture of engine performance.

Don't worry too much about 1 knock. After you flash a map the DME needs to re-learn a few things about how you drive. If you want to improve your 91 gas you might add 2 gallons Ethanol to a fill-up, which improves octane.
