Stock Nismo and TT?

This is normal with forced induction. When you are building boost at part throttle, airflow is already bypassing the throttle plates and building up in the plenum rather than behind the throttles. Regardless if you change the exhaust or not, 6psi part throttle and 6psi full throttle are going to always feel pretty much indistinguishable in engine torque.
