Not for any tuning purpose. It is just a way to take a snapshot of my car's performance. If it is far below my expectation, I will investigate, but the car runs fine and I expect I won't be surprised.
It is another data point for my driveline efficiency estimate at least. Just barely worth $75 to me.
