Tial 50mm BoV

I just picked up a 50mm q and I was wondering what spring to run, I've seen some people say to run the 3, and some the 6.

I have run the pink (3psi) and black (6psi) springs with no issues. Technically the 3psi spring is the one made for supercharger setups. If I get a new valve I am going back to the 6 psi spring though.

what is the exact difference between the two? Why do you prefer the 6?

The 3psi springs allows the valve to be fully open at ~3 inches on vacuum. The 6psi will make the valve open around 8 inches of vacuum. Not too different from one another, I guess I just prefer having a slightly stiffer spring since the pink one is super soft.
