Hondata

Went to dyno yesterday and they say my engine is knocking on Cylinder 1 and they say hear pining? but I didn't feel or hear anything on the way there and on the way home. after that I do a small data log. can someone take a look and tell me what should I do?
CA 91 gas
Stock Intake K&N drop in with PRL Turbo inlet pipe
PRL Catted exhaust
Front Pipe
HKS Exhaust

It is not occuring under load some it is mechanical noise from the engine. Typically it is some part of the the exhaust system making metal to metal contact, but it could be anything that is making noise that the knock sensor picks up.
