PJ- i took the supercharger off and i still had the problem, it is only a powerdyne silent drive kit so im only making 9 psi and the problem isnt under boost it is just regular driving when im at wot it goes great just trying to run around town is the issue. as far as the fuel system goes i have a 255lph pump, holley reg, and a fmu for the stock injectors, with the fmu off im still haveing the problem too. the fuel pressure is where it should be around 38psi so i dont think that fuel is the source to my problem.
as far as vacum goes i know that the boost/vac guage is reading 15 vac at idle which i think is normal, it read the same in my other stang. i posted the codes that i got yesterday, koeo 81 82 95 and koer 94 and 44, so what can you tell me from them?

Right now what I see is: 95 - Fuel Pump Circuit Open-PCM To Motor Ground (M,O)
81,82 codes are related to the smog pump and not an issue. You say you did KOEO right? The codes mean different things whether they were done in KOEO or KOER. Was this car originally an automatic or are you running an automatic computer? Because KOEO 94 is: Torque Converter Clutch Solenoid Circuit Failure (O)
As for the code 95 you did say you have a MAF conversion, here is a link dealing with a code 95 and a MAF conversion (basically you need to add a jumper wire)

Let us know what you find.

At this point, it seems past my experience. This is were I would ask Joel. You can try and PM Joel5.0 here or you can go here http://sbftech.com/index.php/board,20.0.html and post up a thread in his section. Either way when you contact him provide the link here so he has a head start on where to begin.
