Problem with supercharged 94GT, please read (long)

What you said makes sense, but it was fine before the bigger pump went in. It also used to detonate until he changed his fuel filter, then it was fine. Now it just falls on its face when you shift gears, then it will go, but it then throws the check engine light and the code listed above. Does anyone know what too high of MAF voltage means? I imagine the answer lies there as the voltage being high or low tells the computer how much air is coming in, but I don't know which way it works.
He is not running a FPR either, just the FMU and 190lph fuel pump. I think the FMU jacks up the pressure to 72lbs, this is done by restricting the return line.
