Because it's absurd to state that your lightly modified s4 (which = 304 lb-f at the flywheel stock) makes more torque than fully modded ttZ32's. When I have seen dyno's of Z32's posted around here with basic bolt on's that are no where near fully modded that produce more than 350 lb-f at the wheels.
