Doesn't the UTEC have a base map? Run that? If not call TXS they'll be able to help you.

In the UTEC ver4.2 open-loop fuelling paramters, there is a setting for larger injectors... this is referred to as your injector scaling. Set yours to 740cc and see if it starts and runs reasonably. Play with this number a bit until you get the smoothest starting. You can drive the car now but you should stay out of boost. You could raise the OLF TPS threshold (ECU-to-UTEC cross-over point) to 50% and that should make it drive reasonably, but once again stay out of boost as you will get high EGT as the ECU is trying to maintain stoich A/F ratio.

I drove around for 2 months on the TXS stg4 base map with injector scaling set to 550cc. It bucked like hell on transition and ran pig-rich, but was safe.

Estimate of power is kinda moot cuz it depends on what kind of dyno you are getting tuned on... likely range is 270 - 300whp.

Like Blen said, stay out of boost and you have nothing to worry about until t-trix tunes it.

As for boost, with the TMIC you should be able to "safely" run 18-19psi or so on pump, and probably 22 or 23 on C16 if you go that route. However, every car is different, so ymmv...
