'04 Saturn Ion LOG - lotsa KNOCK (false??)

[Boost]

My stock 2.2 Ecotec automatic with almost 124k miles. Logged some random PIDs that happened to be on the screen, so some of them aren't the most relevant.

Picked up a consistent up to 5 degrees (!) knock retard on the low RPMs only under load. Could this be just rich mixture? Carbon buildup? Some false noise?

Engine runs smooth, no hesitation felt and just ran an 11.0 second 1/8 mile, which is funny slow BUT impressive for bone stock and untuned. Hoping there isn't really so much knock on my little 'Tec :(

Here is the log file, thanks for looking!
