hope i can describe this so that it makes sense..
i have a SP mk17 1st stage..
i have an S600 2nd stage..
i adjusted the orifice so that the 600 free flows (hisses slightly) when wide open..
i did this adjustment on a full tank 3400 psi..
just for the heck of it i hooked up my regs to a tank with 600 psi..
the free flow is much much greater at 600 psi then when hooked up to the 3400 psi tank..
i went back and forth, same happened every time..
why is that ???
