Ignoring the BOV side for a minute, if your using an originally OE t28 turbo, you'll probably find that it has an inbuilt wastegate, identified by a little flap on the outbound side of the exhaust housing and a brasy coloured cylinder mounted on the side of the turbo with an arm going out of the centre of it.
If you have one of these, you don't need an external wastegate, however, that said, you can up the boost on an internal wastegate, by using what is called a t-peice boost controller, which fakes the amount of boost the internal wastegate is seeing, there by causing it to open at a different level from normal boost.
Hope some of this makes little sense.
