OK so please clear some things up for us, first are you sure it is a 5.6L? Is it an H1 or is it a HMMWV? And please explain what "light pressure" means, we need more to go on.

how does the air filter look?
Black smoke is too much fuel for the amount of air it's getting, so first things to check are air filter and intake system.
Does your truck have an air intake restriction gauge?

So your scan tool threw a code that the MAP sensor was faulty and not reading correctly with different TPS inputs?
