you will need to get a speedcal unit, which wires into your speedo harness, or you can use something like a superchips programmer, or similar device.

Dallas Mustang Speed-Cal is what you need. I have it, love it.
Ask anyone else that has it too, they'll say they love it too.

I agree. That device is amazing. I have a 99 Cobra and switching to a TKO tranny my speedo was way off. At 60mph it was reading
15 mph. The speedcal was able to correct this. Dont forget the calculator on the Dallas Mustang site. Extremely helpful.

if you're planning on getting a chip or reflash you can have your speedo corrected via either....i'm lucky in that i know someone local who can plug up to my EEC port and change my speed in five minutes
