Does knock and timing have anything to do with fuel cut?

[DJ23GSX]

I was wondering if knock and/or timing have anything to do with fuel cut? I can run 16psi on a s16g with stock injectors mkiv i/c yada yada (see parts list) and get 0 knock and 19-20* timing but I still hit fuel cut around 6000-6500rpms. My injector pw/dc never goes over 19. My o2 volts are pretty low at .80 but according to my knock and timing I should be running great right?

knock= less timing
too much airflow = fuel cut

so now u know, instead of just thinking you know, or not knowing at all
(in my case, it was not knowing at all)

Thanks for the info guys I just wanted to be sure that i was on the right track thinking air flow was the only thing that caused fuel cut.
