Nearly stock torque #'s at low rpm is typical for centrifugal supercahrgers. The faster you spin them, the more boost they make. Positive displacement superchargers, on the other hand, reach maximum boost at roughly 1/3rd of maximum operating speed, meaning you have full boost at 2,500 engine rpm.

The torque curve that the GTM kit makes looks typical for a positive displacement supercharger and I'm amazed that they are getting that out of a centrifugal charger.
