If you look at the airflow curve versus boost pressure, it can't keep the boost up for long. What is the CFM for our v6 engines, 350-400? It drops to 1.5 psi on the biggest turbo. It looks like it is optimized to for low RPM enhancement.
Do they have electric turbos for optimized for the higher flow rates? If so you could use a pair of them as sequential turbos to help keep the boost up at higher RPM.
I'm not sure whether it is useful or not.
