Just to add add to what I wrote.
On the previous page op said he is using the oem knock sensors.
To me that's a fail.
And is unsure of the correct settings, and even mentioned he was registering knock when it wouldn't really be possible.
He then advanced the timing 5 degrees and it fixed it.
This is not a thread about how useful knock detection is.
It is is a thread about how having things you don't understand can actually make things more difficult for you.
Go get your car tuned op! And let us us know.
