Which way do i need to tighten or loosen the screw to make it activate with higher boost? Right now i have it set to kick in the 2nd walbro at 4psi, which is way too early...i am trying to have it come on around 10psi. Will one walbro be ok up to 10psi?

 

tightening increases the psi itll come on at. im good with one to 10psi, but all engines are different, youre making more power, so youll need more fuel, whats wrong with it coming on at 4psi? its going through a fuel pressure regulator so it shouldnt hurt
