A VTA dump valve can make your car run rich as everytime it vents the air to atmosphere to stop back pressure etc. a recirc keeps the air in the system keeping your mixture closer to 1 lambda.

Is this a bad thing  - not necessarily, does it make more noise - yes

choice is yours - or ditch any valve and have some turbo flutter instead - not great for your turbo in the long run but sounds authentically rally
