ok, I didn't get any answers yet.....

my knocking level at idle is 16-20
my knocking level anywhere but idle is 0......

I turned the boost up to 16, stomped on it, and I saw a 2 appear briefly as the knocking level.

does this sound normal?

Fuel cut frequency is rpm dependent. In other words, if the ECU sees 1200hz at 5000rpm its fine, but 1200hz at 3000rpm, it will cut (not actual numbers, just an example). Unfortunately there is no magic number to avoid fuel cut with.
