Another perspective, which makes perfect sense to me: the guy "near" me said, he prefers Power Commander because the work is much more efficient for him. The bike is running while he is measuring, and he can make adjustments on the fly. With Tune ECU, he makes a run, has to shut off the bike, make adjustments, do another run, and so on.
He said in round numbers, he would charge ~$250 for a session with PC, and ~$400 for a session with Tune ECU. He did allow as how with the cost of PC, it could be wash, depending on what a customer wants.
