ITB's
As for "Bowtie", I would add that the ITB's that I manufacture ALL include a LARGE PASSAGE WAY to interconnect to ALL ports under the air doors.
With this method the air pressure is EQUAL at Idle/Low speed to all of the ports AND the signal required by the MAP sensor is STRONG.
As for "airflow" I agree, the size is very important.
My LS-1/2 "stacks' feature a 2.5" (63.5mm) size and are
"aligned" to increase the swirl into the cylinder.
Flow ? do the math !
When connected to any of the heads sold, they will increase the flow of air into the port.
BOOST, sure, no not with the turbo.
The MAP and BARO sensors are board mounted with my ECU's (2 seperate 100% real time)
The result "data logged" shows that on a 101 KPA day,
the MAP sensor will record a pressure of 108-110 KPA in the runner at peak torque.
Thats Boost, without a supercharger !
