IIRC, since it's pre-97 it can't be tuned. Well, at least not flash tuned with HP Tuners b/c it's not OBDII.
Have you tried calling the dealership? They might be able to offer you some direction on where to look.

Look for something in gm performance parts or call scoggin dickey. You might be able to get a factory reluctor ring from a truck with a 700r4 and a 3.73 ratio. Scoggin Dickey is a dealership with a big presence in gm factory performance and there on ls1tech. Hope this helps.
