    My 475hp 1850 tq would do 52lbs of boost for me.

    Sounds about right, it varies some depending on what it is set at but generally they max out somewhere between 35-45 if everything is working right.
    Seeing 52psi on stock fueling means your wastegate isn't opening like it should, which usually results in high drive pressure and heat.

    That would be about right. My BXS put up 55psi with the original 550 file in it.
