This is a bit of an overgeneralization. Tuning should really not be done on an inertia based dyno as it does not load the wheels. This is why Eddy Current Type dynos are used for tuning - they apply load.Can also be achieved by using data logging. In fact, some say tuning via data logging is better than using a dyno as you are putting a real load on the car and are in real driving conditions
That being said, most tuning should be a mix of EC dyno tuning and on street data logging.
