I bought this to fix my speedometer on my 2008 Dodge Ram 2500 Diesel. I was running 37" tires and went to 35" tires to fit a spare under the truck. I couldnt adjust my speedometer with EFI Live that I already had, so i bought this. It worked perfectly without having to reset the truck to stock. It took me a while to get the truck perfectly calibrated but now its dead on with my GPS.
