Default Dump Valve 500bhp Impreza
What would be the best dump valve on a MD321T running 1.8/1.9 bar?

Do you get a rich overrun using a VTA? Can it be mapped out?

You can hear it through the induction kit.

the problem with the oem valve is you can't be certain it isn't leaking and the more boost you run the chance of it doing so increases.
