currently got my old -31 fitted to my new turbo at half moon pre load. so should limit to 7psi on spring pressure. fine for running in my engine and turbo. however once run in want to run a base pressure of about 14-15 then use my bleed valve to sneak the boost up as and when.

Apparently the -34 at half moon pre load opens waste gate at 14. would a -34 be more suitable for what i want instead of ringing the neck out of a -31?
