Also, posting the log along with your current tune file is the BEST way to make sure that you get relevant answers to your question.
Since I cannot see the current tune file to look up values you may be hitting in your limiters, etc here are my $0.02
1. Your AFR commanded vs actual under WOT is off, and is running richer than commanded. Have you attempted to use the Speed Density Calculator yet to correct your VE across the Mapped Points? Rich AFRs in Direct Injection cars can create higher than desired cylinder pressure, which can lead to knock. Also, too many people ignore tuning the Speed Density values on Ecoboosts, which would be like Ignoring MAF tuning on an LS3. Yes, on the surface it appears more complicated than MAF frequency tuning, but HPTuners gave us this awesome scanner and awesome tools to be able to calculate the coefficients needed to properly adjust our VE Mapped Points.
2. Under LSPI Reduction on the Torque Management tab, you may want to make sure that your limits are set high enough for the amount of boost you are trying to achieve. I know it says that it is the "Load Limit", so most people draw the conclusion that this is the Airload value they are referencing (where I see a max of around 2.20 Airload in your log), but from my observations over the years I believe this to actually be a Pressure Ratio limit (Manifold Absolute Pressure / Ambient Barometric Pressure), in which case I see you hitting values closer to 2.40 in your log. Then be sure your Combustion Max table and others related to that limiting are also in check.
3. Looking at your Spark Source in the log around some of your higher KR events (-3.0 or worse in the first pull of the log) you are hitting your Cylinder Pressure Limit (See #1 about Speed Density tuning recommendation to get your WOT AFR closer to commanded)
