I just got done with my 500 mile service, which surprisingly took a little less than an hour. But when I got there, my odometer on my 2019 chief dark horse read close to 600 miles. When I left, I didn't look but when I got home I noticed it now reads 399. About 200 miles less than before! Is that normal? Everything else is running great. I did noticed it looks like they flashed a different ECU because no matter how hard I went on the throttle it took forever to get to 60mph. I will reflash my fuel Moto tune asap. Anyway, I'm curious to know about the odometer mile anomaly.
