My camaro has a lid and recently installed an ls6 intake. I just started using the tuner again, I am hearing a considerable amount of spark knock above 3000 rpm at WOT. Do I need to retard the timing, or also increase fuel? Some basic tips would be helpful. I always run 93 octane.

I'd say first monitor your live data and watch timing and KR to see if what you are hearing is really knock.
