need help with techincal Q's
Just got BNR 2's and Greddy SMIC. Now I was goint o buy the Pettit ECU that is tuned for all bolt ons and 14.7 PSI. But my question is, if I put that in will I automatically be running 14.7 PSI or do I have to do something to the turbos? Also, I know I need fuel upgrade. How bad if bad at all will it be to run the engine at 14.7 psi for about an hour to the fuel upgrade shop to get injectors and fuel pump installed?

The Pettit Limited ECU has fuel cut at 14.7, the Unlimited doesn't.
The boost will go up to Fuel Cut as far as your car can take it (i.e. if you have the airflow, the boost will hit 14.7 PSI). The stock fuel system can take it, as long as all components are working properly (your injectors are flowing correctly, and you can sustain fuel pressure).
You cannot run larger injectors on the Pettit ECU. You can run additional injectors if you also have a controller for them. Otherwise, you'll need a programmable ECU like the PFC or Haltech.
