The video is mor than likely
The video is mor than likely JUST showing the supercharger tune kit. with out the injectors and tune. When you throw in those 50 lb injectors and the tune is when you get the 475 HP at the fly wheel. 427 to the wheels..... I've seen in person a 2012 mustang v6 with the procharger kit on a street tune with stock injectors make 412 RWHP.
