Get a quote from your dealer or someone who has the hardware and software to do it. Otherwise, it's going to cost you $200 for a device to do it yourself.

So, after the new tires ,my speedo read about 2-3 MPH under the speed limit at 55-60 MPH. I got the superchip flashcal and set it for 34.5 (based on dimensions from the Nitto website) in tires and it read about 5 mph OVER the speed limit. I tried to set it 3 times and each time I plugged it in it said my tires were 29.5". I finally went back to the stock settings resolved to know I am going about 3 MPH over the speedo at 55-60 MPH.
Any suggestions?
Thanks,
