Why does that matter? Well, your torque curve looks really, really flat, but that's partly because the scale of the y-axis is stupid. If you took that same graph and put it on a proper set of axes (say, up to 175hp and 175ft-lb) the torque curve would look like everyone else's. Looking at the numbers at the bottom of the page, your mininum torque was 137ft-lb @ ~2500rpm, and peak torque was 154ft-lb, a spread of 17ft-lb. On my dyno graph the difference between torque at 2500rpm and the peak torque is about 19ft-lb - essentially the same.

Those are pretty impressive numbers, particularly for a car without cams or headwork. Your numbers are basically the same as the numbers my car put down on a Dynojet, and Dynojets generally read higher than Mustangs.
