John,

Your close and that is easy to fix.

You are experiencing high boost at low rpm due to the high load created by "mashing" the pedal at low rpm in a high gear.

A dyno tune will not fix this as it need to be road tuned so grab the laptop, hit datalogger #1 to induce this condition. The log will tell you where to reduce timing.

Knock will most likely be under 3K but in load sites 80-100 only. Reduce timing by 2 degrees under these conditions. Take a look at the STG3 timing curves in the 100% load column to get an idea.
