I was watching a video on the new NSX and the fact that it is a dual injection system like our cars (direct & port injection) the manual states that "Under high-performance demands, the port injection system supplements the direct injection system, feeding fuel into the intake ports where it mixes with the incoming air for increased power production."
Sounds like what you guys did to aide in the fueling needs of the S/C with the stock fuel system without going to larger injectors
Just realized I didn't update this thread with our latest improvements to the ISF SC kit:
Stage I upgrade: Dyno below is of our SC running the original SC pulley with no increase in boost level, just tune update, upgraded fuel pump, and e85 gauge. Optimal e85 content for this level of boost is about 45-50% e85 mix. Good for about 570whp:

Results below are the "Stage II" tune, pulley upgrade for up to approx 8psi boost, plus using an external controller to operate the port fuel injectors (in addition to the e85 gauge and pump upgrade). Optimal e85 ratio was about 55%.
