Also I'm not sure of this since I've never owned a 6 banget stang, but if they have weaker fuel pumps then he may not be getting enough fuel. Or it could be a dirty air filter. (believe me it happens). Start with a basic tune up. And as for the rear end it should be the same basic 8.8 in the other new edge mustangs!
Update I made friends with a guy that builds mustangs in Kentucky where I just moved to,and he told me that the motor is a 4.6 bullet motor do they resemble a 5.4??Im trying to get pics up just working crazy hours.thanks
and be like every other :trip:with $4k $5k to blow and thats just for the "centri" not including everything else this guy would need to even hold that supposedly 420 to the wheels to the pavement and it be useful. you can have all the power in the world but it gets you now where if you cant use it!!
