You can’t go wrong with reducing the area by 2 degrees at a time. When you mentioned this issue to your tuner did they reduce timing in the area. It could also be false knock.

Attached is my custom tune from etunez, 3 datalogs, same tank of gas, done a few days apart.

I have been having issues with what seems to be bad gas, for some reason the first log was the first time I filled up with another brand and thought my issue was solved, logs 2 and 3 are on the same day ...

Car should work fine with canned tune until I find a decent etuner.

Thanks
