Slight Knock Retard in Logs (Have CAI)

Haven't tuned the CAI yet. Just figuring things out on my own. I've found a very tiny bit of Knock Retard during ramp-ups. Still, i'm pretty sure KR is bad. Its the Chevy Performance CAI - the car is stock otherwise. I've only just started to learn how to tune. Is it possible this is the CAI not getting enough fuel when I start pushing close to WOT? It seems almost like it's just running a little lean in those cases. See attached.
