I've recently put in a superchip and it didn't make a whole lot of difference so I'm wondering about putting a Jacobs Ignition system in my explorer. I've got the Jacob's Ultra Team in my Mustang and it seemed to make a big difference so I was wondering if it would do th esame for my Explorer. My explorer in an automatic with the towing package with 3:75 gears. Has anyone had good results with thiers? Thanks for the help.
