So it's possible you may be running a little lean with o2's in that range

With the my 9c1 impala, im seeing 9* of KR at WOT
my LTFT's are at zero, and fueling seems near perfect.
im suspecting my unknown mileage injectors are clogged as my IPWs go pretty high . Ive changed a few things on the fuel system and everything was on its last leg and had massive build up and deposits. If this doesnt do it im removing my 300k cat.

god i cant wait to get rid of this motor and entire fuel system.

Have you tried running 93 octane to see if its false knock?

Those are def some good possibilities.
