Speedometer Calibration??

[camfoot]

I have bigger tires on my 97. Equivelant to 33" in height. My speedometer is off approximately 10 to 12 mph. Can a normal tire shop calibrate this or do you have to have a scan tool attatched by a mechanic? If so, then how much does this usually costs?

Scantool to calibrate speedo, probably a higher end bi-directional like a Tech2 or the like.....

Thanks lester. You were right. Tech2 scantool. I will get it done soon. you know how appointments go, whenever they can get me in.......

Some other Bidrectional tools can also adjust this, but the Tech2 will do quite nicely.....
