I need an education
I want to learn more about the function of the MAP sensor on the 6.0~ Anyone got the real scoop on how it works/controls boost? Maybe I missed an existing post, but the searches get several hundred hits. Lil' help?

The MAP (Manifold Absolute Pressure) sensor reads the pressure in the intake manifold (through a hose) and sends a signal to the PCM (Powertrain Control Module) that tells the PCM to adjust the injector pulse width to fit the amount of turbo boost. Essentially it controls the fuel/air mixture as the turbo boost increases.
So it's not controlling boost per se, it's monitoring MAP and feed fuel appropriate to the boost level.
There's a decent graphic of it and some more info at

That concludes the limit of my limited knowledge
