Must have missed this question.
Used an AWD dyno. Car rated at 550hp. AWD peak number was 434 hp (21% drivetrain loss). After was 510hp at the wheels. Using the same drivetrain loss, would result in 645hp. Same for torque.
In fact, in the lower rpm range, the gains were even greater over stock.
In addition, there were several before and after runs and all were within a few hp of each other and the same awd dyno was used to ensure accuracy and consistency.
