I found this thread and I liked it, I have a 91 Ford Explorer, made in December 90, Eddie Bauer, 4 doors, automatic, 4x4, 3.73, the change to manual transmission, 5 inch lift, a friend bought a 92 very similar, also the modified transmission occuring manual, and Rancho lift kit installed 7 inch, same axis ratio, he modified the pcm, install center force, and still does not run as hard as mine, feels that lacks power . Actually I failed to know what is due, your engine is 97, mine is the original, limited my speed in 4900 while no longer have that problem, my clutch is factory design and still managed to do things that can not be modified in. He asks me if I did to mine, but the truth is not to be due.
