I have had a Ford Certified FFH for about 2 months now. We have put nearly 3000 miles on it. We live in the mountains of Western NC. Nearly 1/3 of the mileage was a trip to Florida on I-575 and I-75. We ran 70 to 75 mph in both directions, with mileage at 43.8. Our FFH has had the calibration firmware installed. This last weekend, travelling home from Asheville, NC, I was following a truck at about 50 mph up a 7% grade. There was not a bit of hesitation to pull out and pass on a 2 lane highway. The FFE accelerated nicely even at that grade and was at 65mph quickly on that 7 to 8% grade. Don't be concerned about the power situation. Oh, and even with the changes of elevation of two thousand feet or more at several different places, mileage was 46.1 mpg. It is really great to be able to recapture some of the energy expended going up by regen braking going down.
