That sounds like exactly what happend to me.

It's still stuck under 10 psi.

I kind of doubt it, btw the water injection is off
right now.  It seems like some kind of mechanical
failure, clogged fuel filter, bad fuel pump, or maybe
even a coil going bad?  It's so strange because the
only thing it seems to be related to is boost psi.  It
runs great at all rpms, but as soon as you hit 8-10
psi it starts to misfire, and the A/F gauge goes all
over the place, but seems to lean out.  I'm also
thinking maybe a bad engine block ground?  I'll try
and rule a few of these out tonight.  I've also beeb
data logging with both ECU's, and can't find anything
out of the ordinary.

Thanks,
