12:1 is an extremley high rise rate...for every pound of boost, your raising fuel pressure by 12lbs.
id REALLY get away from the fmu, get a set of properly sized injectors and a 2 bar map sensor from an alltrac or mr2T, and somthing like the SAFCII or even better emanage or SMT6 or 7 to control them.
thanks for the props =)

:edit:
the probe injectors are what 330cc or somthing?
thats actually pretty close to what you need.
what are you doing about your stock map sensor?
if you were to go to a 2 bar map, you could get rid of the FMU, and use somthing like the SAFCII to tune out your fuel curve.
with the option of using a better matched turbo to the car, you ST guys should really be looking into maximizing everything else in the setup to make it more durable, and bulletproof.
the FMU is really old school stuff, and really should be abandoned for our setups IMO.
there are much better, safer, more controlable ways to do it.
