With the 08 STi, fueling will resume regardless of boost (only the engine speed threshold comes into play). This seems to be precisely what they are talking about. So, likely the fix is to lower the boost threshold (currently an unobtainable 24 psig at sea level).

Wow, I actually started mimicking the 02 WRX style fuel cut (with added retarded timing, 8 degrees at rev limit with the base timing tables) and a soft throttle cut on the 32 bit ECUs that I have tuned.
