Doing a quick peruse of the comments, if I missed it, one thing you should do which is the real story of what is going on in the combustion process of what you do and have to do.
Perform a plug chop to see how the burn is. What happens at the plug is the story being told in reality. Unless you have a dyno then you get the high tech version but I would suspect dial it in with a chop and then dyno to fine tune if necessary.
