I would set the shift points with the rpm setting instead of the MPH setting
I would set +200 rpm also would set +4 Global timing .

+1000 is too much.

where is knocking with +4 , if only at W.O.T you can -3 for low med and high

timing.

When it is knocking is the throttle on the floor. if it is adjust wide open timing on mid range and high range to -3
