Torque Converter Modification from Import Tuner mag

There is a guy in Herkimer NY who modifies Torque converters.All he does is basically cut fines out of the converter making it a higher stall converter.Guess he does good work from what I here.He cuts them open,removes a certain amount of finns then rewelds them and balances them.Google search maybe he has a site.Don't know if he does Import converters but pretty much a torque converter is a toque converter I would think.
