Get rid of the AirTex fuel pump and go with a Motorcraft unit from RockAuto.

What does the fuel trim look like? Short and Long term. Did you test fuel pressure? Also you said your friend has a "badasss" scanner? does it have cpabilities to do a cyl. contribution test? How about fuel filter? Obviously a vehicle in gear uses more fuel, therefore possibly a clog???????? If you could make a list of all things done or tested so anyone trying to help doesnt have to read entire post:->

Have you checked to see if the injectors are firing all the time like they should or checked the resistance to see if the are in spec? Also, what about swapping the ECM with a freinds if you have one or going get one from Pull-A-Part in Baton Rouge?
