Tuning with jets, Power valves and an O2 guage

Well, I think I will back out of it. I am in complete disagreement that a fuel issue is creating your problem, so I don't need to participate in this one. I know fuel issues can cause this to some degree, but not to the degree you're experiencing, IMO. Since you're working on the fuel here, I don't want to get you off track.

I was working on everything, not just the fuel. I have tried everything I know plus several things suggested by others. I am not convinced of anything yet because the car still knocks!
I can't really get off track because I haven't made any improvements yet.
