OK...got ahold of Mike at 5 star.
This is what I said to him:
I have a 2011 Expedition with 6k miles on it. Since new, I have been very unhappy with the lack of power and poor throttle response. On hot days it seems like it won't even pull a hill. When it downshifts, it seems to loose power instead of gaining any. I even took it back to the dealer because I thought something was wrong with it. They said eveything was ok. There has been alot of talk on the forum about the '11s not having any power for some reason. Some have suggested a tuner. I was going to try a superchips flashpaq because a freind has one on his Jeep and recommended it. "Solisimo" from the forum recommended not using a canned tune and that I should contact you. The vehicle is stock. It is my wifes car, but I drive it as much if not more than she does (we work together). I have been very happy with the gasmileage we are getting (17-20mpg) and I'm scared to mess that up. I would just like a little more power/better torque/better throttle response/ better shifting. Any insights/recommendations?
This is what he said to me:
Hi Vic
thanks for inquiring, We can honestly help.. a 87 octane tune will enhance the power and shifting from the expe.. The biggest things to remap is the Drive by Wire system in the vehicle and the transmission maps. Your mileage will be stock if not better no worries ... Call me tomorrow if you want to talk more about the stuff we can remap to make the expe run like it should have from Ford. We are open on Sat. 9am eastern.. 843.250.0499
thanks
Mike
I am going to be the guinnea pig and give this a try. I'll keep you all posted on how it goes.
