My 00 mountaineer 5.0 it has tq monster headers flowmaster exhaust intake spacer cold air intake. And a 89 octane henson custom tune. I dont have my truck wot very often, but when I do floor it when its at high rpms the motor spark knocks bad only at wot and high rpms. My air fuel gauge is all good so im not lean. And there is no check engine light. The truck runs great mid throttle no problems only at wot high rpm. Any ideas
