Maybe its just me and my untrained eye, but your car doesnt seem to like the drop off in cam angles around 8500. The ignition stays the same so I cant imagine that being the cause of the raise in knock level.(though as a side note i think this car could use a degree or two more ignition at WOT) Also...

Those cam angles are crazy man. LOL. 40* @ 2200 at WOT? 30* at low cam Xover and 50* at high cam? The gear cant move that fast...You can see in the datalog the gear trying to catch up...

Id start with the Toda Header kal and tune from there if your 02-04...otherwise use the 05 kal and add fuel on the high cam for the header.
