I have a 2002 Z06 with full bolt ons and I get a random knock in 4 gear from 3900-6500Rpm's. I have changed the plugs, wires, and injectors. The injectors helped quite a bit. I filled up with unleaded race gas and the knock is still is there and also pulled 10 degree's of timing. I'm certain that this is a false knock, I even logged a completely stock Z06 and it has the same knock in that range. I think the LS6 has a very sensitive sensor

How do you De-Sensitizing the knock sensor in HP Tuner?

Thanks

It's most likely something rattling at that resonant frequency. Find out what is shaking around and fix it, they knock sensors are not "too sensitive", they need to be there unless you're willing to risk engine damage should you get a bad tank of gas etc.
