Does anybody know if the Hypertech Speedometer Calibrator will work on other fords? I called hypertech and they said it doesn't have coverage for it, but I'm not sure if they said that because they haven't tried it on another car and don't want to sell me something they're not 100% sure about, or that each car needs it's own programming setup. I'm thinking where the tire size memory value is stored in the car's pcm is the same address, because why not reuse already written code?

I'm asking here because I'm sure you guys have run into a problem lifting a truck to non oem specifications. The dealer said they couldn't do it because the ability to do so was removed by ford in 2015 to force people to comply with factory emission standards. I have an edge and I went down a tire size so now my speedo is off by 5 mph, and it's really irking me.

Or if there's a different way I can fix the deviation could you kindly let me know? Thank you!
