This same effect can be achieved by changing the throttle mapping in the tune or with a throttle manipulating device like pedal commander. i have testing this first hand with a larger TB, pedal commander and changing mapping in the tune all individually and every combination thereof.
All that is happening is the larger TB at say 10% throttle is now open flowing more air as if stock TB was really open 15% so it "feels" like it has higher response / torque delivery when driving around but that's also why peak numbers at WOT do not change unless you have FI and have a greater demand for air than the stock TB can fulfill.
This is also why people have no throttle "coasting" high rpm/higher speed issues because it is flowing more air at zero throttle input than it was before.
