I was looking at the SAE papers on the 3.6L SIDI V6 yesterday. Interested in how much headroom was in the stock fuel injectors and fuel pump. The fuel pump has a bit of range in it,and the SAE paper even mentions turbocharging. By my math, there should be enough high pressure fuel pump for about 550 hp at the engine. I haven't figured out the fuel injectors yet. DI is a bit different with the fuel injector calculation. The SAE papers mention a few different styles of injector, even a few flow rates, but I didn't see a duty cycle that I could figure out.
