We just wrapped up our development on the 2010 Ford Mustang GT and have some dyno numbers for those curious about the output of the retuned 4.6L.

Does anyone else think that based off those numbers that the 2010 4.6 is underrated from the factory? It puts down 290 to the wheels, that would mean only an 8% drivetrain loss. I would say that the motor is actually around 330-335 based off 15% losses. Also very impressive 10HP jump just with a catback.

That or they took into account what aftermarket companies were already doing with tunes and CAI's. Just my thoughts tho.
