knock?
 

First off i have a power fc so i can monitor the knock. Im not boosting at all right now, not even to 1psi, but under hard acceleration i get a squeeking sound and my knock sensor goes nuts. It spikes then drops then spikes. I think its just picking up the squeek sound becuase it seems to be related when i watch it. I guess my question is what could that squeek be, and why is it setting off my knock sensor? O and it only happens when the engines under load, like low rpm in a high gear, when the throttle is more than half open.

Thx guys for any input, cuz im stumped.
