My Speedometer is off by about 6 mph after installing lift/bigger tires.
What do I need to do in my 03 WJ to get the speedometer adjusted?
My dealer tried re-calibrating it with their ODB scanner...but the factory tire size-setting was still wrong.
I don;t really wanna spend $300 for an advanced tuner/scanner not knowing if it'll work or not.
Are there any speedo-Jeep shops in South Dade that can reset it?

If it's anything like a TJ, you just need to change the speedo gear. It's like $70.
- 2000 TJ with big rubbery tires for going on trails and stuff.
