    Lately I’ve noticed some audible engine knock/detonation-
    i went down from map 4 to map 3 then map 2 and now map 1-
    still hear some slight ping on accel
    can see the ignition 1 dropping as it detonates-
    same drive same fuel same everything no changes
    does not do it on factory tune-
    im afraid to to a WOT log
    any ideas?
