almost 18 counts of knock. Yowza.
I'm still new at this but I will say:
BoostEst of 48 and near 100% duty cycle.
Have you boost leak tested / compression tested? I assume you are not running 48 pounds of boost.
Am I seeing the same log? I only saw 5.6* of knock.
Things are way off, you're not pulling 46 lbs/min on a 16g @ 4400 rpm.
