    Digital Tuning Anyone know this Superchip?

    Pulled this out of my 89, guess a previous owner put it in. I had no idea it was there. Anyone know what it does? Only thing to identify it is the microchips really. Looks like there used to be a sticker on the guard covering the microchips but it's long gone now.

What bothers me is the molding/trim that’s in the fenders...
