Default knock problem

I have a very strange knocking on 2300 to 3400 RPM on 0.5 to 0.6 gms/cyl only while all others range are ok (no knocking), I tried to reduce the spark advance but nothing?
I have a +10 on all the table, and started form -3 till +3 on that range and nothing.
I did decrease the sensitivity of the knocking, but I was adviced not to.
so what to do?


2005 Tahoe, 5.3, compcam, Gr MAF, AIRAID induction, Ls1edit 1.5.
