I am running the SD 2 BAR as well.
I was getting some knock from the burst knock table.
Check there as well.
If that is the case bump the delta air for the burst knock up.. stock on my car was 0.04, I went up to 0.20 as I was seeing changes of about 0.17 with the turbos.
Someone found it for me.. hope that solves it for you.

Yea, bust knock is common when first setting up an SD tune since your airflow#s can have large deltas. I don't remember it showing up in the normal KR pid, but there could be one that combines the two.
Anyway, just 0 out the burst knock table and see what happens.

Have you tried running more timing. What happens when you run it at about 15* in that area?
I'm guessing this is either false KR or something bad is going on. How is your PCV setup. It can cause some nasty Knock problems. Also check all your injectors and read your plugs
Keep us posted.
