3.55 on my Limited.
I will say after driving the Raptor for 2 weeks, the Limited feels a little more quick off the line and agile - noticeable but not huge - you can feel the difference in tires - the 35's weight over the stock Limited's 31's on 22" wheels. With the Raptor, you feel more planted and in charge and the height difference in the Raptor seems noticeable - due to the tires and whatever they give you in the Raptor suspension. MPG's where really nice on the Limited at about 17.5mpg to 18mpg in the city, 22mpg on the highway. Raptor - getting 16 in the city - so not so bad.
The interiors are basically identical (802A package) - except the colors. It seems they pumped a little more exhaust volume into the Raptor's cabin. (I wish I could turn that off... Can you?)
I like to offroad and I was trying to turn the Limited into an offroad truck which was just a mess of parts. The Raptor - perfect as it is. Not going to modify it, that much - can't wait to get it down to the Oregon Coastal Dunes.
