correct me if i'm wrong
ok i am trying to understand how the engine management systems work on these trucks from my understanding the truck reads a signal from the MAP sensor telling a computer how much boost the engine is making then in return the computer adds or subtracts fuel??
so if a truck had a dusted turbo that had stage II's and a chip could the dusted turbo be the reason the truck does not really come alive to 2200 to 2300 rpms?

There is no boost sensor, the MAP uses a voltage signal to tell the PCM what boost the truck is making. More boost = more MAP pressure.
No boost till 2k rpms? Oily sheet, that would suck!
The dusted turbo could easily be the reason you aren't making good power down low... it's not gonna do its job right until you replace or rebuild it.
