hhmm.....i just had the speedo calibration checked and it was dead on all the way up to 70, which is where they stop comparing since we don't have any speed limits greater than 65 here in va.
if i got ahold of hp tuners and made the changes, as you show, how would if effect the car even though i wouldn't actually be replacing the tires. would this only effect the speedo readout, which i would then be able to change back after the calibration check ?

You certainly could change it to impress your friends on how fast your car is!
I think speed is referenced in other tables too, perhaps active handling and traction control from memory, and certainly for automatic transmissions. I honestly haven't paid much attention to it.
Another thing you could do for sure - you could put a speed limiter of say 30 mph on the car. Then you could load a "valet" tune in your car before you park it. Of course that would be a huge pain... unless someone could figure out how to make HP Tuners work on their Windows Mobile phone and got a USB adaptor.

I don't know... I suppose it would affect the odometer too, so if you wanted to cheat your mileage you could do that. Not that I would condone breaking a federal law.
