Possible injector issue??!

Two days ago under a hard run I heard a pop and truck started running terrible, massive amounts of white smoke, rpms jumping around bad... Thought was the bully dog I had on it so uninstalled that and after a few minutes of running cleared up and ran fine. Fast forward to today the smarty s06 finally got here installed it on level 4 60hp no added timing to compare it to the bully dog and what a difference... Decided to play jumped to #7 160 added timing and it hit around 2900-3100 rpms and right back to the white smoke terrible idle the works, it's following along with a injector issue but since iv never seen one go out on these motors I don't know for sure any help or thoughts?

I have a fuel filter full of grime and some metal shavings, clearly not running on all cylinders,
That is pretty definitive. If you have metal shavings on the fuel filter you have issues. Those came right out of the fuel system via the return lines. Missing on one cyclinder is a dead injector, the massive amounts of white smoke could be one or more gone.

Likely what happened is the CP-3 is eating itself up and spitting metal into the injector and return system. The black on the filter is normal,m it is just wax and content form the fuel, metal is NOT normal.

Time to pull the injectors an CP-3 to have them looked at or replaced.
