Default Off idle knock at track...suggestions??
Went to the track today and noticed that I'm getting 4-6* of knock right off of idle during the launch. The rest of the run is fine.

Any suggestions on how to get rid of this?

Could it be false? Like something hitting from torqueing over on the launch.

Had that happen in another car. Only would happen on the launch and turned out to be the downpipe hitting the frame, so it was false in my case.
