Give Forge Motorsport a call, they were really helpful when I needed one for my GT4 and ended up designing a new one to fit my car! They worked on it till it was just right.
I don't own this anymore - I just can't be arsed to change the picture

Just  recently had the same discussion with myself, forge, hyperboost etc  ???

Anyway, decided on the Forge DV 007 and just received and fitted it today. Results are yet to be confirmed but have just been out for a quick spin and it has made the car a lot more smoother and responsive, and I think (maybe it was just me like) but the turbo whistle was a lot more noticable as well.

 ::)any chance of a quick update as to how your dump valve has been performing?  Looking at buying one myself but am in two minds like yourself.  Any regrets?

Just bare in mind that I know nowt about cars apart from what I've picked up on various forums.
Before fitting the DV, my car was really starting to surge and jump about, not holding the boost when going through the gears etc, and generally wasn't a very nice driving experience. Anyway, the original Bosch DV was making a horrible noise when lifting off the gas, as though it was catching on something, not the normal phssst (??) sound. I know it's hard to explain a sound but anyway !!!!
I could have went to the local stealer and replaced it with another bosch unit, but read elsewhere that these could also fail at any time. I don't know if that it is true, but have read that on more than one occasion.
So I decided to splash out once and for all and go with the Forge 007 (as opposed to the 006 which apparantly can have difficulty in fitting under the enginer cover) due to other peoples experience with the unit and also the fact that it doesnt  need any maintenance.
Fitting it was a piece of P, even for me - 10 - 15 mins and it's on. Since installing it around 1500 miles ago, the car has been completely different to drive. It is now a lot smoother through the gears, pick up on changing gears is instant and turbo lag has dropped considerably.
The weekend I changed it , I had to go to Barnsley with work and took me own motor and can honestly say that driving down there was absolutley brilliant. Although I'm sure I might have been done for speeding on the M1/ A1 (paranoia maybe??) and I'm just waiting for the speeding ticket  :'(

I can also confirm that the Forge DV007P is a great upgrade.
