I did this yesterday and it took me about 10 mins, at least 5 of which was getting the damn OEM hose clips off! I just used one silicone hose from the inlet manifold straight to the DV.
Went out for a test drive and the DV and throttle response was so much better. And no hesitation when lifting off or part throttle. Smooooth
For the cost and time involved against the results it's well worth it!
