I'm not an expert on this matter, but a couple of questions come to mind. What is your dash boost gauge showing? If you were getting 24PSI over atmospheric I would think you would be pegging the end of the red range. Is your Autometer boost gauge measuring absolute pressure, or differential? If absolute, that implies that you are only getting around 9-10 PSI of boost over atmospheric (I'm guessing max stock Aero boost pressure is around 15-16 psid, and the cutoff probably occurs around 18 psid). That could explain why you aren't getting fuel cutoff (on my CSE, which has a slightly lower boost/cutoff than an Aero, the cutoff occurs around the middle of the red range on the dash boost gauge). If it is differential, like your dashboard gauge, with this kind of boost you would be smoking a G35 (and sooner or later your engine). A bad BPC should not affect the fuel cutoff function.
