If all you did was change the injectors and forge the engine you should be fine if you have a wideband and a standalone ECU to bring down the fuel in the lower revs to advoid bore wash on the break in progress. I did the same thing when i forged my engine. Went fully forged with the same setup except the injectors. Went from stock to 550's on the rebuild because was planning on running higher boost once engine is breaked in properly. If you have a little knowledge on your ecu and know how to use a wideband your good. 6 to 9 psi should be good to run it in. You could also bring it to your tuner/mapper and let him run it in/setup the basic fuel on the dyno and when you reach the 1000miles you could go back for the complete and more agressive tune and higher boost.
