On your 07, the speed-set speed control has nothing to do with the actual speed acquiring or display. The speed-set touch pad basically tells the ECM to hold the speed at the set point, up the speed when up arrow is pushed or reduce the speed if the down arrow is pushed.
IIRC, the 07 shows both digital and analog speed. If both show a delayed reading, id suspect the paddle wheel.
