So I decided to put on the 3.1 pulley and tuned it a little. Here is a quick scan I did on the way to work. The car was at full temp as I had been driving it for about 45mins.

Here is another scan I did on the way home and the tune was the same. But notice the knock? Maybe the IC was heat soaked from driving on the highway for 1hr.
Any ideas why it would start to knock out of nowhere?
