Power is made by torque and revs, torque isnt made by power, so its perfectly normal to have tons of torque without the power if your not revving and are running loadsa boost.
The way they made it is mostly down to big big boost pressure.
Though being able to "only" have 300bhp or so and not having to rev meant they could run mega high comp, very low duration cams, small ports, etc etc, which all help torque too, but in a much smaller way.
If a 400bhp "normal" spec mega boost and mild cams YB stopped revving at 4.5k or so itd also be pushing similar numbers, though obv not as good as they have been specced to breath well at higher rpm too, which obv reduces low down power and torque.
