Oh, you will LOVE it! I still can't wait to drive my Fusion in the morning after 9 months of ownership, thanks to Bob's TORQUE! tune that I am running in my car. It simply rips through the gears now and I saw over 120mph on the freeway last week (I don't recommend those speeds, however). I love the mid-range thrust now. Mileage has also improved from stock. The 87 octane tune is great, the 91 even better, and the 91 torque is my fave. About 1mpg improvement over stock with the torque tune.
