Another speedo calibration question

[MegaRocks]

Is there any other device for an 06' truck to change speedo calibration other than the Superchips Flashpac?



My dealer already put my tire size to the biggest that DC has for their dealers 285/70r 17. That is only half the way to where I need to be for my tires: 35 12. 50 r 20.



Anyone know what else to do?

Bully dog programmer does this but only on their monitor. It doesn't change the speed at the speedo.
