*help*! could it really be knock??

[boostedawd]

Car: 93 AWD talon 5spd 180,000mi, mods:k&n, hacked can, stock mas,14b, mbc usually set at 14-15psi, ported 2g exh mani, 3in t-back exh, supra tt fuel pump, aeromotive afpr 38psi,s-afc, iv got as much as 40+ counts of knock around 2000+ rpm, at like 15 20% throttle, it happens alot when im trying to accel away from a stop sign, light ect. Even if im in nutral, and i give it a quik blip of trottle up to 1500-2000 rpm more often then not my logger will show like 4,5,6,7,8 counts ect..it varies. Seems to me like my censor is overly sensative or somthing. Am i getting what is know as phantom knock?, or could my lifters be triggering the censor, the head was rebuilt by mitsu about 40k ago. any suggestions?
