Quick Speedo Question

[STREETSIDE]

My 97 Cobra Coupe currently has 4.10 gears and a 23 tooth speedo gear installed by a previous owner. I am not happy with the accuracy and when I recently pulled the gear out most of the teeth were gone anyway. So I want to go back to a stock speedo gear and do either of following:

1) Use a Dallas Mustang SpeedCall.

2) Use an SCT Tuner to correct it.

What is the most accurate of the two options above? I was just going to do the DM SpeedCal but noticed that some places like American Muscle actually add the SCT into their kits for correction. So I guess an SCT tuner can give you same speedo correction as a SpeedCal? Plus the SCT would let me clear codes and improve performance too?

Last Question: The stock speedo tooth gear is 18, correct?

SCT speedo calibration only works in 99 and up cars.

Thanks. I'll just go with the 18 tooth gear and DM Speed Cal then.

Can anyone tell me for sure what speedo gear came stock on 97 Cobra? Would it be an 18 or 19 tooth gear?

Also with the speed cal you will be able to adjust it for gear changes and different size tires.

Call SHM, they can tell you. They sell the gear too.
