Injectors

well i think realistically with a fpr, fcd, bigger fuel pump larger injectors bout 18psi but i would watch out for those turbos hehe... they have ceramic wheels and have a habit of dying
also you may want to look at getting your fuel rail modified so it is fed from both ends and exits out the center... that way you will 99% not have any detonation problems
if you want to miss all of those bits you can just up the boost right to 14psi as your ecu can deliver this and just buy a fcd to get rid of fuel cut... altho beware of spiking issues or anything that may cause boost to go above 14psi
