I was looking around on the internet because i am going to be putting gears in my automatic mustang. i cam across this, http://www.superlift.com/products/misc/truspeed.asp
i wonder if this would work to correct my speedometer. Any one know? is there any other product like the speedcal for automatics that is realitivly inexpensive?? I also found this http://www.fast-diesel.com/cummins/era.html
just curious if anyone has any opinion on these types of modules to correct my speedo
