Get rid of the blow of valve, no need for it unless you want the Woosh sound. Then just maintain it correctly. But you do not need a tune for it. In fact you can't even tune for the bov. When I got my car it had a hesitation under load or you can say coming into boost. Turned out my fuel pump was going out.

If you have a good tuner local they can diagnose a bad fuel pump by simply pluging in their laptop and seeing what the car is doing.
