hi guys

I have one of these fitted, had it for a while now

Got my boost up at 17psi and the dump valve only seems to open properly when i take to foot off the gas compleatly, if i just take my foot like 95% off it just pidgeons.

Any ideas?

Which way round do you have it? Also where do you have the vacuum feed connected to?

[BigG]

the vacume feed is connected to the stock location with the stock hose and i *think*(at work currently) the bottom of the unit is connected to the boost source and the side looping back to the air intake pipe

That all sounds fine - check the vacuum is the standard one. If its still not working try removing the DV and checking that the piston moves freely.
