Compressor surge?
Quotes from (2) different turbo info sources:
"Compressor surge: You can think or surge as the point at which the compressor blades begin to “slip” in the air, losing their pumping ability, much like an aircraft wing loses its lift when it stalls. In a turbo, this happens in a series of bursts, as the blades slip, then bite, slip then bite. This sets up a pulsing wave in the turbo piping and explains why the sound has that characteristic “flutter”. "

Compressor surge rarely sounds like flutter, surging you will know by the rpms of the car rising and falling in a rythmic cycle. Our Supra's do this with the larger head units if they aren't optioned with ported shrouds or anti-surge compressor covers.
