Curious to see what it was I'm basically having the same issue. I'm not on link unfortunately. My issue is from a dead stop to about 2200 to 2300rpm. I'm extremely confused on this issue.
So I have basically the same issue with my 1ga Eagle Talon Tsi. I have the knock sensor that has the connector piece on it but the other side does not how do I go about getting it connected so I don't have any issues. Pictures if you have any would be great.
