I seem to have some tip in knock right now as well but really just a few counts every now and them. Nothing is being pulled because of it, but I may try and adjust it out.
Right now I'm dealing with dropping KC's at high RPM with no change in IAM or Advance. I pulled my WGDC back to drop max boost to see if it cleared up but it didn't so I think it's timing related.
I gotta start working on my website now so no more long info posts for a while.
