    OBD-1 tuning

    I have a buddy with a 92 5.0 that needs someone to do some diagnosis & tuning. This 5.0 had a supercharger on it but was removed before being sold to my buddy so it is probably still tuned for the supercharger. It has an erratic idle and seems to be running rich. Any recommendations for someone who works with OBD-1 computers?
    Thanks!

    those older pcm didn't get flashed.. they had a chip piggy backing the pcm.. have him pull the pcm out and see if there is anything plugged into it at the opposite end of where the main connector is....
