Make sure that if you get the popping on acceleration that you have the correct map in the FP. You may want to contact V&H for an upgrade on the map.

With replacement slipons and intake, it's not unusual to get the popping on decel. Check that the mufflers are on the pipes all the way and the clamps are positioned right.It could also be a gasket at the joint of the pipe to the head.
