The 1406 is only 2% leaner than the 1405 (not enough to matter in this application).
The issue you are experiencing is when you push into the throttle, not while cruising. Therefore you probably need to adjust the accelerator pump calibration to compensate for the airflow change and keep the fuel delivery at the optimal level when you do.
