its on way but it has green spring...
I'm afraid you're going to want a yellow one. Green = 5-15psi, yellow = 15-23psi.
I run a yellow spring with 1 shim.

so i need to order kit from forge for like £20?
Your flow looks very healthy. If your dv is in the stock location it doesn't need an uprated spring as the boost is acting on the side of the piston and so no way can it affect its operation. If however you have relocated the DV such that boost acts against the botom of the piston it can leak boost, in such situations you would need more than a yw spring to stop the boost from leaking past. Much better to connect the DV the right way around in the first place and stick with a stock spring as it will operate most rapidly. Forge say that the DV can be connected any way around which is true to a degree but it can leak if altered from stock orientation.
ive just ordered it!
oh well, to be honest im expecting to just take the old dump valve out and put this one in.
Everybody ive spoke too reckons i need yellow spring.
