Default Getting knock

Top of second and all of 3rd at WOT. AF on the dyno was right at 12.7 in 3rd with no knock. Knock in third on the street is as high as 7.9*. I did notice that my injectors are maxed out, but as long as the AF is good I figured I would be good until I get 8.1 injectors. Timing when the knock comes on is 29.5 *, and drops to 19-23*. Any help would be greatly appreciated.

if your injectors are maxed out, i'd look into some bigger ones soon.

glad to hear you got it cleared up though!
