What does TSB stand for?
If Honda issues a TSB for the S2000 it would pertain since its a fix for something. There have been some TSB's issued in the past but since you have a new 03, your new car comes with all the past TSB's already performed so no need to worry.
The TSB is not the same as a Factory Recall. The TSB is a bulletin informing the Service Department, should they come upon a recurring problem, on how to fix or repair it.
Usually, TSB's must be performed within the factory warranty where Factory Recalls can be done at any time after the warranty is over.

So, it should be done for free, depending on the problem, and of course if they decide that you've been over revving
,or so they say.
