where can I get a Diverter Valve from if anyone can recommend a uk company think revision D is what I need ?
Thanks
Mass consensus is that Revision G is the one to get.
The Rev D is a piston valve, and while more 'reliable' by design, they can still seep pressure.
Rev G is the latest and greatest diaphram valve. Holds boost nicely and works like a dream. I had a new pcv, cam follower and Rev G fitted a couple of months ago and it made a massive difference.
Since then I've had a remap and it boosts consistently well, so I'm sure the Rev G was a good choice.
Think I have a p/n somewhere..
