the reason the torque is down is because it's a low displacement engine.
horsepower is what tells you the true power of an engine. torque is a misconception that many people have
say one engine makes a constant 100 ft-lbs of torque up to 8000 rpm and another makes 200 ft-lbs up to 4000 rpm
when gearing is applied, both engines have the same exact power. and infact will have the same horespower reading-- the reason behind this is the first engine can do 100ft-lbs twice at twice the speed the second can make 200ft-lbs.
it's also the reason why people are not correct when they say that compared to the LS the GSR has no low end torque, the dearing is completely diffferent, the gsr has more power thourhgout the band.
