Has anyone done a high level of tune but retained the AFM?

I know the general findings are 320hp, but what is the highest output achieved with an AFM on a big turbo, intercooler, injectors ect?

I know past its full open point it cant meter the fueling, but if the wide open setting is rich enough to support boost past that point, is it the air flow that limits it to 320 hp? or is that its last metering point?

It's the air flow that limits it. IIRC after about 3k revs it has no idea about air flow anyway.
