I have a problem at 6000rpm exactly in third gear I had a greddy type S the first time,.. I just bought the greddy type RS and i VTA both times and it sounds like the BOV is opening up and leaking boost,.. I have installed both BOVs properly.

The weird thing is ,... the BOV will hold 19psi the whole way and of course drop to 16lbs in every gear when tje wastegate opens,.. but when 3rd hits 6000rpms, the noise begins, sounds like slipping belts at first,.. then if you listen closely, it sounds like the BOV letting air out like its wide open,.. the car doesn't acclerate until I shift into 4th its like a "vacuum limiter" or something anyone know anything about this???
