Check two things for this:
1) The vacuum amplifier (BFS) has an input from the vacuum pump. Measure the vacuum at this line to be sure you have full pump vacuum (above 20").
2) The amplifier also has an input from the VCV. T into this line and run the gauge to the cabin and drive the vehicle. See if you get a quick 15" from the VCV at idle and the delay in vacuum rise is eliminated. If so, then you've confirmed that the culprit is the amplifier.
