not sure about the new auto's, but i have the speedometer calibrator from dallasmustang.com. its electronic, goes into the trans and has to stay plugged in permanently. not sure if this will work for you car or not, but something i did when i put the 4.10's in. could check into it.

the tuner should do the trick. is it reading 10mph too fast or too slow? are you sure its off by that much? you could always try setting it as 4.10s or 3.50s depending on whether its too fast or slow to see if that makes it a little closer.

Are you sure you installed the tune correctly? The handheld should have taken care of it.

A tuner should correct the speedometer. One thing to check is the dia of the rear tires, are they the same as stock?

hmmmm i really don't know why it would be doing this. i guess i would try setting it as 3.50s for ****s and giggles, but i really don't know if that would be considered a fix.

and truebluejerseyshore, who cares? i've seen waaay worse. to be honest, your post looks similar to the OPs. relax...
