Just a quick plot on its own, I'm lazy:
VS the shape of the others in the first post (it's not as rough as my Tuner set, but still not smooth either):
Best way to tell is to use an OBD-II datalogger (I like the Android App "Torque") to do some realtime graphs of the throttle position feedback, then go do a few accel runs and look at the instantaneous history on the phone's screen, compare to your butt impressions. You'll notice the dead and/or too-sharp regions if you have any.
