   I've wondered about that myself. I don't have any actual experience but
I have a feeling it wouldn't work. Or, rather, wouldn't work as intended.
I can see how hooking up the brakes to a static vacuum source would help in
a low vacuum situation, but for EFI, the computer actually uses the value of
the MAP sensor to help determine engine load. If the vacuum doesn't change
in varying atmospheric and engine load conditions, it seems like the
computer would be getting false data, and like they say, garbage in, garbage
out... ?
