It sounds like it made a huge difference in the performance. My wife was just complaining about the "push the gas, wait then it goes feeling" she sometimes gets. I need to convince her to let me tune her Expedition. My F-150 has been running a canned superchips tune for about two years now. I never liked the soft shifts and the slipping feeling in the transmission when you would get on it from a stop. Why Ford does this is beyond me. At least the canned tune took care of that, but i hear that Mike is a genius with the transmission mapping, and your post seems to prove it again.
