most people will advise you to swap it for a solid butterfly disc and get a dump valve. "Turbo's make torque, and torque makes fun"

It'll open really slowly, giving a nice whooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooosh instead of a WHOOOOSH.

It is there to reduce hydrocarbon emissions on overrun. |

IIRC on all cars it helps prevent over run, also I think it helps prevent turbo stall. If your engine is set-up properly and looked after over run shouldn't be an issue, and if you've got a DV turbo stall shouldn't be an issue either, so you might as well go for a solid disk as the valve impedes the air flow in the carb.
