Knock under WOT
I'm running the Quad race box on the 100 H.P. setting and under WOT I am hearing a knock or some kind of noise that sounds like detonation. It does not seem to do it on the 65 HP or stock setting. I'm not running the 140 HP setting because it drains fuel pressure to nothing.(working on getting new pump now)
Could this be a fuel problem? I've read about the injectors making noise but I don't have any noise during idle or normal driving.
I'm running about 40 pounds of boost when it happens and fuel pressure is two PSI.
As an after thought I started hearing the noise after the turbo install. Could it be the wastegate I'm hearing?

It's probably timing rattle which is not supposed to be a problem. Mine does it too but it seems like it's mostly when the truck is cold. It's not so bad once it warms up. It got worse for me once I did the tone ring mod and I ended up having to back that off some...
