Anyone know what fuel pressure the 600 efi should run @?

Currently have the fuel pressure regulator set to 35 psi. I played with setting it at various levels (30, 40 & 60). Seems to like 35psi the best (both response & plug color).

However, it still has a low end Bog?

1000ml

im pretty sure it is around 30-35 psi. the bog isnt due to the clutches is it?
