Because turbochargers can only be efficient over a certain RPM range. They wanted to have lots of torque at very low rpm which means having a small turbocharger. The downside to that is that the torque is going to fall off at high rpm, and that can clearly be seen in the provided torque curve. So the desire for low rpm torque indirectly means that engine will be unable to make torque at high rpm. So in order to achieve their power goals at a necessarily lower rpm they needed to run more of boost.
