when my car has a boost leak at the intake it shows no power under 3k rpm then when there is enough airflow it will have power at higher rpms.
so you could still have a boost leak that becomes negligible once you have enough air flow.
one way to test it is to pressurize the boost tract from turbo to intake to make sure there are no leaks.

to trouble shoot the pressure converters without buying an extra part. swap the front pressure converter to the back and the back one to the front.
