I assume at the end you were talking about how i brought up WGDC. You seem really fixed on the numbers, which is a good thing for digging into the details and comparing the thresholds, but you also need to look at the actual shape of the curves qualitatively. You can usually see right away if something doesnt look right as most curves should be smooth. See screenshot below from your log, you can see WGDC is erratic and in turn this effects everything from boost to AFR.
Absolutely, thanks for pointing out the WGDC that definitely helped me figure out the issue.

I have heard others in the B58 community state that cylinder 1 timing seems to drop more than others. It's interesting because I notice the same phenomenon on my logs.
