But if I floor it then I still get a pretty wicked drivline vibration. It still feels like it's coming from the rear.

Recall that the center section (aka diff) is mounted in rubber. As torque increases, the upward deflection of the pinion nose increases. At a greater angle between the driveline axis and the pinion axis, there will be greater vibration.
