Overboost?? Stage 2 AEM 93octane

I know there's been a few threads about this but I was hoping to post my log and get some opinions. I recently got the parts put on and loaded the stage 2 map, and here's a couple of runs that I logged. I trimmed the fat from the logs but can provide the rest if its important. My parts:

-AEM Intake
-UICP
-Perrin dp + high flow cat
-Buschur v2 quiet exhaust

Without having much background in this, i'm thinking the knock sum of 3 might cause concern and 28.8psi is probably overboosting. Should i try LWG map?

Update:
I switched to the Stage 2_aem_LWG map to try and get the overboost to go away.

Now i'm torn. It was successful in eliminating the overboost - I only hit 26.1PSI max through 3 runs WOT. However, i'm also seeing much more knock with this map. I only hit 3 knock counts once on the old map. Now I have seen as high as 6 knock count! I got consistent 3-5 knocks through 6-7krpm on one pull, and random 6 knock count at very low rpm (1000rpm, casual driving)

Any thoughts?
