If you are going
to "Do it  yourself"(DYI) then I would get a pressure regulator and bypast
the
pressure to the CPU.

I don't think under any circumstances anyone should bypass the press./vac
line to the cpu. I don't know if that's what you're trying to say, but if
so, you're probably not going to get as much power (curve) as with it
connected. It would annoy my to have a check engine light on all the time
for it, too. All this not mentioning blowing your engine apart.
