This is really the big issue on the GM 6.0L. These engines make really nice HP and torque, but to add longevity of the transmission they used torque management to choke off the engine so it didn't kill the tranny. As BenK stated, it's all about duty cycles and there is quite likely more torque the transmission can handle. By reducing the torque management you get more of the power the engine makes delivered to the transmission.
