6.0 injector cackle

[2006PSDSD]

I have heard about 7.3 injector cackle, but does the 6.0 do it too? The reason I ask is when I run my truck at WOT with either my Street tune, or Extreme race, I get this loud (its louder on the race tune) rattle or grinding sound coming from the passenger side engine compartment area (that's where it seemed to be coming from).

I just read about the 7.3 cackle and it sounds similar to what I'm hearing. Am I on the right track? Will a regulated return fix my issue, before I kill an injector?

I dont have a tuner but I do have a RR and an Air Dog, It did quiet it down some but it still cackles. I just road with my brother in his 7.3 and his truck is way quieter than mine and he has a Tuner and a stock fuel system.
