how is it piped up? should just be the pipe from the underside of the plenum and a vacuum pipe that goes to it. and what kind of noise does it make? a whoooooosh or a chirp or other?

Yeah - I'd guess you've got no vacuum on the back of the piston.

As I asked on the other site; pictures?

I had a bailey dv 26 was absolutely shite only because i've done the 4 hose loop to the throttle bodies for more vacuum after seeing mightymods on youtube lol

It works even better with a stronger dv John with that mod the dv26 just stayed open as too much vacuum holding it's diaphram open,because of that I was loosing so much boost,much better with my sard one though!
 
I did that mod too, my normal vaccume line was clogged up so i did the MOD mentioned above.
I haven't had any problems with my dv26 though :S

On the ports with caps over them; they're for balancing the throttle bodies when you set them up.
You could also use the inlets from the PCV if you've taken it out.
