I did attempt to dyno my car before the headers, however our dyno was malfunctioning and we needed to have it re-calibrated. (I generated 1.2HP and apparently over 8 million foot pounds of torque...).
I would call 15% loss somewhat inaccurate, and more likely on a conventional or somewhat antiquated automatic. Perhaps when the car is transferring power via torque converter, but the automatic does achieve full lockup in almost all operating situations.
