Hi all, i have a recurring knock retard with my cammed 6.0 and im struggling to pin down why exactly this is happening. i suspect that there is no real knock but i am unsure. this problem does not appear to be consistent to my eyes, however right now the issue seems to be occurring in the 2000 rpm range which also happens to be where my exhaust is the loudest, could it be that i have abit of my exhaust rattling around causing these issues? im working on my ve tables still and these tunes are in speed density. thanks for any help
