how accurate is the mph?

I'm betting that its better than the OEM speedo.

It's driven off the same cable as the speedo so it should be the same.

so it only reads correct if you run stock tires

Or if you've got the right speedo gear for the tires you have

My Scanmaster is 4MPH off due to the 255/60 15" tires in the rear. I believe that Eric at Turbotweak can program that into the chip.

4MPH slower on Scanmaster than in reality. I forgot how I measured the 4MPH difference though. That size tire looks like it was made for our cars, it looks pretty bada$$.
