Thats wild. As piston speed increases the likelyhood of autoignition decreases... maybe the ecm is throwing a lot of advance at that part of the curve too.

My timing on the top end is around 24* iirc....stupid low timing if you ask me.

I used to run one oy old malibus at 15* initial and 44* total...ran awesome too
