I agree with what Jay-Jay said...
And add-in... you can make the tool for a TBS with very little cost, and it will actually be better than the electronic models. Here is a you tube of one:
Google is your friend on this subject. Search: "home made throttle body synch manometer"
What Jay-Jay was saying was that during those first 6k miles there are various mechanical things that are getting comfy in their positions. Perhaps one of the 4 valves will settle-in slightly different than the others... (just an example). People often think of this as the valve stems stretching just that tiny bit. Thus the early valve adjustments are often more "productive" of a smooth ride than the later ones. Extra care in getting all 4 valves perfectly on-specification and you will notice great improvement.
In addition the throttle bodies should always be balanced after a valve adjustment. You want the air/fuel mix to be the same on both the left and right hand cylinders... if you change the valves even just a little bit they need to have the air/fuel vacuum to be re-set.
Many times the technician who is in a hurry doing your routing 600 mile first service will not actually do a physical TBS, but may rely on some electronic hocus-pocus. This, alone, is worth doing it correctly yourself.
Building a plastic tube manometer ought to take about 20 minutes, including the first beer. You can make it fancy and take an hour or so, and still spend about $10.
