Forgedump valve spring

[xJabZ]

Hi, I currently have the green spring inside the dump valve, should I get an upgraded spring, if so what colour?
It is currently on stage 2 running at 272bhp..
any recommendations?

If you were going to change spring then yellow is the next I believe but if all is well then why change ?

Exactly, was it mapped with the green spring? If so, no change needed. Mine was mapped with the yellow spring, but the green one suffices (k03s at 1.3 bar).
