It doesn't need to be exact. You just don't want it so loose that you lose boost. I guess it's more of a situation that you want to make sure you're not leaking boost when you've found a sweet spot.<snip>
my question is, how would you know when the adjustment screw is tight just enough to hold boost at redline????
Definetely makes a difference!does playing with that adjustment screw really make a difference???
ive tried all open, and all closed, and seems to be the same.
