If you are running a 3.4 pulley that is too much for a top swap. I need to be on E85 in order to run that pulley.

And just to double check, you are using an L67 MAP and tune right? I dont think the L36 tunes like to see boost.

Third, what is that A/F column? commanded Air/fuel? because every time it drops to <14.7 is when it starts to knock. I can't tell if this is the cause or an effect.
