Are you talking about a CHANGE in throttle response or just the normal fly by wire mapping of gas pedal vs thottle plate?
Since I often drive over relatively big things at 0.2mph (think drive up onto a curb), I love the mapping curve that gives me control in the 0 to 3 mph range where a linear map is useless.
If your mapping has changed there is likely a problem either at the pedal sensor or the throttle position sensor.
