My speedo and I'm sure odometer is off about 5%.
How do I fix this on a 2004 ranger XLT 4x4?

Thanks!
Jason

I recalibrate mine with a Dakota Digital SGI-5C. There are newer models now but they should still do the same thing. There are posts on TRS about it. Click on Search to find out more about it.

Thanks. It appears a used tuner might be the best option and gives extra features.
Now I just have to work through the vast number of brands/models to figure what works for my ranger.
