need help with spark knock

[workingdan]

I just put a cold air intake, 70 mm TB, 4" intake pipe, and a percision upper intake on and when I was test driving my car I get knock retard when the boost comes in. Any idea what could be going on?

Check the generator to see if it's rotated to far down and is hitting the idler pully bracket.

I never changed anything to do with that. I looked anyways and all looks good there.
