2004 6.0 lacks power
i've just completed the egr delete on a 2004 super duty.. all the white smoke has cleared out.. truck idles great.. i let it cool and sit overnight for a morning test drive and while cold wouldnt spin on wet grass.. after it warmed up to normal operating temps it has gotten somewhat better but is still lacking some serious power.. as the phrase goes it wont pull a string out of a cats a** ... it did throw a code for boost pressure not detected... i've checked all connections (wires and piped ) and cant find anything that would help me.... anyone have any ideas or thoughts?

This is most likely where your answer is. The Manifold Absolute Pressure (MAP) sensor reads pressure in the manifold and determines boost pressure. Without seeing boost pressure, the computer does not know how much fuel the engine can burn properly and is probably defaulting to the minimum.
I would say your MAP sensor tube is probably not connected between the MAP sensor and the manifold properly.
Below are diagrams of what your MAP sensor looks like, and where it is located.
