Even so, 10* is quite a bit more than the average guy runs even with 94 octane.

 

I also noticed you are in the 140-160 cells at redline, according to you nearing 30 degrees of timing. I'd check for boost leaks....which would also explain the ability to survive such high timing with such little knock.

Could just be the way the stroker kit responds perhaps? Not familiar with the stroker tunes.
