I recently had my 1993 Trans am tuned. I have stock gear ratio's which is the wide ratio t56. I put my eprom in and my speedo reads out at 250 mph which is where my tuner set the speed limiter at. He did not realize I have the 11 tooth reluctor ring instead of the 17 tooth every other t56 has. So now what I am trying to figure out is what diviser to use to get my speedometer working again. thanks
