Default please help weak 6.2

Hello glad to be here.

I got an older 6.2 diesel with a banks turbo kit and loved it tell last week.
The problem: it's loosing power and just getting worst mechanically it still runs good but just getting slow!!
Got new fuel filters. I Noticed the worst it's getting the higher my exhaust temps are getting and less boost I'm getting.
Please help!!!

Are you hearing any vacume leak sounds, you may have a leak in one of the silicone coupler in the turbo piping or check the vacume actuators for the turbo and lines.

I've check for any leaks intake or otherwise. It's got good take off but after a few seconds it just cuts out. I replaced the lift pump and it ran good for a week but just getting worst. Ho and another thing that I noticed is wen the power cuts out the motor quites down and it don't sound like a diesel any more, no clatter like a diesel does.

Here's an update, today I noticed that one of my injectors is leaking from the threads, would that be my problem?

High EGT and low Boost could also be from exhaust leak per turbo or maybe cross over pipe can also be bad air filter
