why dyno readings wouldn't be affected. Going to the NA rear-end gives you more torque to the wheels in the lower RPM's, right? Isn't that the advantage of the gearing change, so that off-the-line times are faster? I would think that with the torque shifting from the high side of the RPM band to the lower side, you would see higher torque and HP numbers early in the RPM band vs a TT rear-end, with all else being equal. Maybe max output remains constant, though.
