Yeah I have seen knock. What I did was do some 3rd gear pulls and keep taking out fuel with the afc til I got knock. Then I backed it up about 2%. I bet all that smoke might have had alot to do with it since I've been running my car like that for the last 3 months. I have done VERY MANY wot pulls with it like this too. You would think my engine would be toast if I was running that lean anyway. Also my timing is 19 degree's advanced.
You guys should let me come back and finish my last 2 pulls smoke free!
