I never knew Ford used a Bosch system in these--even for a short while. I thought they went from card to the EFI, and then to the Sequential EFI which gave a nice boost to power and economy. I had a '79 4 cyl Mustang as a commuter car. I worked with a guy who had the GT with SEFI--he had gobs more power AND used less fuel. Technology was amazing.
