Ignition timing set?
Winter or summer blend e85? How old?
Any idea what your intake temps are?
What AFR are you at?
What ignition timing values are you seeing?
How do the plugs look after a pull?
How old is the knock sensor?
Any other engine noises?
How does the oil look?

Phantom knock doesn't exsist, the sensor is hearing something, weather it is a major deal or not is what you need to determine.
