I wanted to put the 87 performance tune on my 2001 expedition, but there didn't seem to be a way to load that file as I navigated through the installation screens even though the installation booklet seemed to show it as being available. The shift points seem smoother, but gas mileage hasn't changed.
Superchip Cortex Programer
I installed the programer in a 2000 Expedition 5.4L. The orginal PCM had a superchip installed on it in 2000. The new programer was required after the PCM was replaced. It appears to be as good if not better as the orginal superchip. I like the easy of installation and the new menue for different mode of operation. I would recommend this product to a friend. Thanks!
