Has anyone put an adjustable fuel pressure regulator on their Speed Six?

As we know the Speed 6 leans out at high revs due to the injectors going beyond their duty and not delivering sufficient fuel. Consequently would upping the fuel pressure in the fuel rail quickly sort this problem out, or is it a bit more involved than that? idea
