Once you reach a certain level of airflow, the Power Stroke's stock turbine housing becomes a restriction. Banks developed the Quick-Turbo in conjunction with the Garrett Turbo and Ford/Navistar, to eliminate sluggishness out of the hole and produce strong acceleration. Quick-Turbo produces massive torque right from idle, achieves a higher peak faster, maintains more boost through the powerband, and doesn't over-boost.
