De-proker and over De-porked

Mind matching my P47-D30 with HTC chart datas when Wep is on? I'm 10 MPH short even when I fly with 25% fuel, No Amo.
Note I'm not talking about turn, not about climb, not about acceleration... just about basic top level speed, should be no blahblah about this, it matches the HTC chart or it doesn't.
But who cares after all? I love the P47 and I still fly it and not only in B&Z.... thus I do!
