im geting knock retard all over the map .alot in the cruising range that wasnt there when the blm was 120 or less.as far as timing i started with a stock map and went down and i should have been able to go up a little withe cam i have. its not to agressive but a little more than stock. iwould like to add an egr but my intake doesnt have a spot for one and i dont want to buy a new intake.

are you getting knock in cruising range or power enrichment? it sounds like your power enrichment AFR is too lean to me. if it's knocking in cruise range, you probably just have too much timing advance.

also fyi 3900 counts isn't necessarily a lot of knock, when a knock event happens, it's typical that it increases hundreds or even thousands of counts all at once just for 'a few knocks'.
