Alan, the CIS3 system can easily supply fuel to past 10psi, it starts leaning
out around 12psi IME.  No need to richen the CO or anything like that, just
set it to 0mA, you may have to retard the initial timing somewhat.  There is
not any problem with the pressure differential across the injectors and
manifold pressure that I"m aware of.
