You mean record their wideband in the logs?
No, you certainly do not have to do that, especially if they are able to then provide you with a graph after a WOT pull.
BUT, it is ALWAYS recommended to record any/all of your WOT pulls on the dyno. That way you can go back and review them, wideband readings or not, the information is still very important.
