Well finally some positive progress.

I'm using the much scaled back injector flow of a DHP V1.5 tune. Looks like she was a rich knocker. I actually don't know why having the injectors slowed down is necessary for my mods. The LTFT's are still a little more off than necessary, but a MAF tune should help that.

Some PE knock remains, but I have yet to try the V1.5 settings for that. I'm quite confident they will help.

Will report back. So far so good.
