Also remember, when Tuned there is not much difference between the Motors. They end up REALLY close to each other in power if you are going to go in that direction anyway. REALLY weird that a performance package dos not add the ELSD!
Although in the order guide. (XL, XLT, Limited/ Stealth Edition and King Ranch) are all grouped together. Which is opposite of the spec sheet. But that section of the order guide has all sections marked TBD. So that is slightly concerning.
