Pushing through other SUV ́s/BOV ́s at partial load gas blow

Hello together, I know, I have been driving the area with my Greddy Type S for six months now, but I have a question about it now. I hope that someone has dealt with the topic even more than I The Greddy valve is quite comparable from the construction with a closed forge (see picture). I have found a nearly perfect setting using the adjustment screw, but only approximately. If you accelerate e.g. from 1,500 revolutions, the loader then The engine swallows up a little bit later and you go some of the gas during the turn-up. It is absolutely a push-up, but rather a feeling, as if the tank is empty and the air is already sucked. This is very minimal by setting it up, but I just can’t get it completely away. can this be because the greddy is not hit by the pressure coming from the pressure tube, but longitudinally (like the twist recommended by Forge). In theory, it could be that the valve opens too early, the charging pressure is already pressing it, because the control pressure including the spring tension is too low compared to the force due to the charging pressure still attached to the throttle valve. Should I perhaps twist the valve, so change the connections? What about the open BOV ́s? Has someone noticed that? They can only be mounted like my Greddy, because they j a now only have one connection. And now the big quiz question: who knows about it?
