You just remove the 2 hoses from the bottom of you EBV and fit them in either end of the bleed valve.

yep, works this way on all valves I think.
BTW, does anyone know why the EBV has 3 pipes??? What's the point of the third one (I think checking inlet pressure just before the turbo - pointless me think!)
cheers

The third pipe is to take the bleed air back to the intake. This is because the intake air has already been "measured" by the ecu and bleeding it off to atmosphere will knock the fuelling a tiny bit. Will make it slightly richer if anything.

i've fitted the prv & when in the right gear for the speed it holds 1.2 bar in every gear but if i use a higher gear than than i should for the speed it overboosts to 1.3- 1.4 bar, after 1-2 seconds or until i pick up speed then it drops to 1.2 bar & holds. is this right?

AFAIK, a spike of over boost should not make a problem as far as you have 1.1-1.2 bar on the red line..
