Wrong again. Most knowledgeable tuners do their startup, idle, and low load and partial throttle tuning before they make the car owner put it on the dyno at $150/hr.

Many well-known tuners offer both options of tuning on the dyno or street. Almost all of them did before the Mustang and Dyno Dynamics load-bearing dyno gained popularity. Dynojet 248s (the most popular dyno) are inertia dynos, so partial throttle tuning, and fine tuning are usually done on the street when using them.
