I am getting knock at 5100rpms and higher?

[wh1-Denver]

We dropped the boost to 15psi and still got knock, I am gettingit at 5100rpms and higher. Thinking maybe it is in the valve trane. I have T&D 1.65, weber 206 .528 lift roller, rollmaster chain, comp cams roller lifters. Any ideas?

do you have a scan tool...how many degrees.....could be a false knock as you said...is it at 5100rpm in 1 st 2nd or 3rd....if it is in third that is alot of Strain on the motor what are your o2#'s

We are pretty sure it is fasle knock since I still get it @15psi and i have a PTE fm intercooler and alkycontrol progressive kit.
We are hinking it is in the valve train or timing chain. We are using DS and Julio aka Razor says it has to be flase. I need to track it down and eliminate it, I have an audible knock sensor and when it goes off I lift in fear of damage.

Make sure the downpipe isn't hitting the frame.

It better not be with the H&R Parts poly engine mounts. They don't move!
