Anyone have any ideas on where to set the Steeda Timing adjuster when running 11:1 pistons? The factory stting is at 10 but I still get knocking at 5-6000 rpm when I tromp it. If I retard it back, how far should I go? Or do I just play with it and retard it back until feels and sounds right? I'm getting a dyno done in a couple of weeks, but until then..
