Kevin,
You're way to used to posting in the DSMLink forums. For the guys using only an SAFC, lb/min airflow and g/rev don't really mean much
g/rev is the mass of air per revolution consumed by the engine, its one of the factorys the ECU uses to determine the appropriate fuel and timing maps to use.
Like Kevin said, pulling 30% out with the AFC and then only running 10lbs, the ECU is almost on a cruise map!
Your best bet is like Kevin said, up the boost CAREFULLY until you can start flowing enough air to get the ECU to run the maximum airflow timing and fuel maps.
You can check your plugs to see the condition they are in to see if they need to be replaced. A suction or whistling noise is normal through metal IC pipes, but it might be in your best interest to do a boost leak test to see if you have any leaks. With a 60 Trim you can get away with running boost around 20psi without damaging anything, if you are tentive when tuning. I.e. watch your EGT gauge, make sure things don't get too hot, ect.
