actually...i bet you could have tuned it pretty well, but to have NO knock isnt believable. i bet you could get it down to a couple degrees. torque management has a lot to do with knock. until you tell your computer how much torque youre actually making then it just knocks on the big end because its doing that to prevent detonation by itself. i went from 10* to 1* with just tuning alone (on a 3.2 pulley, with the meth turned off [rockers/headers car]).
