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.

The only gas in my area is 91 octane with 'up to 10% ethanol' added. How does this fare vs. 93 octane? I feel restricted to do anymore tunes than a stage 1 without 93 octane..

As jimmy stated works. I personally just do single gear pulls. Also make sure your car is a full operating temp or you will get knock

Do either 3rd gear or 4th gear which ever you have balls for. 4th tends to slip tires less and puts heavy load on engine

4th manual mode, sport plus, TC completely off, roll along at 2k rpm, hit log then pedal to the floor and dont let up until at least 6k rpm. Then read log

Yep, I forgot to mention Sport + and DSC fully off (hold 5 sec). Drive around until engine oil, coolant and trans oil are up to temperature.

Many guys have no probs running Stage 2 on 91 fuel.

Just in case...(not!)
Never use octane booster, it coats your engine in orange dust. Bad for o2 sensors long term.
