Speedo recalibrate

[Cowpie]

I always check my speedometers in my vehicles when I first get them. I do it via a app on my phone that uses the GPS satellites to track distance and speed, and also those road side radar setups usually found in construction zones. All of that agreed that my 2500 was running about 1-2 mph slower than the speedometer said. Once I put on the next size tires, everything matched up to the speedometer.

I just did the same thing yesterday. I used my Sea Tow app on my phone. It was dead nuts accurate with the speedometer.
