I will be running 5 small jets: 1 pre tb jet and 4 direct port jets, but first I need to do all the primary adjustments with a single pre-tb jet.

What ambient temperatures are you running at?
Do you have any knock at partial throttle after long idling in a traffic jam?
Do you have stock internals?
Lately, ambient temps have been 85-90F during the day, and 75-80F at night.

Every once in a while, I see part throttle knock, but it's random and never more than 1-degree.

Yup, still on stock internals. I plan to dial back my tune until I can build the motor and replace the clutch.
