My Forge 007p DV was in need of a service so I found the old standard DV and ordered a servicing kit. The plan was to service it lapping the valve in and then get it anodised black.
Well since then there has been numerous threads on versions forums and FB about how much all these fancy after market DVs leak. Bills bubble tests on a few different DV and found only the standard DV doesn't leak also that it'll hold out for more boost then I'll ever see!
So I've just put the OEM DV back on. Sound wise it's the same as the forge one only a lot crisper (mine needed a service). So it's staying fitted and my forge DV is going on eBay.
Also I've just ordered a few more goodies today!
