I think they are talking about your first scheduled major tune up. You know, things like plugs, wires, coolant, tranny fluid. Other things like air cleaner and oil still need the regular. The problem with a 100k tune up is that the plugs almost bond with the head, so when you try to take them out after 100k, you bring the threads with you. Then you end up with a new head. Just stick with the 30-40k intervals and you will be fine.
