It's a two part test, the blower door tests should use a thermal imaging camera, otherwise you never see where drafts come from as the thermal imaging camera lets you see the cold air moving inside the walls, not just it's exit point.
I agree that insulation should be your prime focus, if you can afford to lay tubes for a ground source heat pump then do it, but if your choice is to lay ground source heat pump tubes or add 4" of foam to your foundation walls then I say insulate and seal as you can never have to much insulation.
