The 2650 supercharged 6.2L V8 LT4 in the Corvette C7 Z06 makes 15# boost and that's basically what you have, so... I didn't know that.
So, back to your first question on pullies. Mine has a 9.18 lower which is popular, and 2.625, 2.75, and 3.00 upper pullies. You could try 3.00 or 3.25 upper, but I would and did ask KaTech or LPE or Vengeance or some reputable shop about pullies
