I'm amazed that people are still complaining about this engine. Other than the lack of V8 sound, this 3.5 makes the 6.2 look silly. Step on the gas on Sport Mode and the truck takes off! Torque hits early, and the truck flies...why all the complaining?
If gas hits $4 a gallon again and they put a supercharged 800hp 7.0 liter motor in this truck, sales will drop like a rock if it get's 6 mpg....
For me, I'm happy with my fake sound in the speakers, my twin turbo whine, and a Raptor that to me is better in every way than my 2013 was, even if it is 2.7 liters smaller in displacement.
