There's no requirement to data log, but once you've determined that the tune is running well initially, I would at least log anytime something notable changes with your car (additional mods, conditions it is driven under, etc.) or when you notice something is not right (feels down on power, hesitation/stumble, etc.)
Up-pipe is fine for stage 1.
