From a conversation with them that is why they go with Silly Rabbit Motorsport turbos which have a different center cartridge due to the OEM becoming a restriction.
I have not found a vendor with a built engine that released data on which turbos they chose to use and why.

AIR flow is airflow though... lets talk real engine physics. If the turbos can make 850whp then they might make less PSI on a lower compression/ported head engine but it should net the same HP.
