Does anyone know which way the adjustment 'screw' should be turned to allow the 'dump' to occur EARLIER?

My car needs fine tuning as when I let off slightly under boost the dv does not let go, I get the WRC 'flutter' and the 'trying to stall the turbo' feeling.

I think I need to back it off slightly (?)

Thanks in advance, MD.

No-one else in the UK got an HKS dv?

Looks like I will have to buy a Bailey then...not.

hi The screw on the end is for adjusting preload on the spring becouse some cars have more vacume at idle than others. So if it stalls at idle its needs the screw winding clockwize(inward) to preload the spring to stop the valve from opening & the engine stalling. that all hope that helps
