so i have upgraded to the fp green and am still running on my 560cc injectors. Boost is limited to right around 16 psi or so and im not running over 100% injector duty cycle. When i am in boost my afrestimate is like 8.2:1 I figured that the knock i am seeing at this time is rich knock. Can anyone verify that i could be seeing rich knock. I am not over running the injectors and i have all supporting mods. Maybe i need to increase my timing or decrease fuel. Some help would be appreciated.

I cant open your log, but you are definitely pushing the crap out of those 560s @16 psi on a FP green.

I maxed out my 550s @ 20psi on a 16G.

It's about airflow not psi.

Anyway you should get a wideband, not sure how you "Guess" what your AFR is.

Tune for 11:1 AFR or zero knock for WOT boost.
 
It's hard to tell you what to do without a wideband. That's seriously more knock than I've ever seen in any of my logs and I was running stupid rich in the past.
