Speedometer reading is not accurate
I noticed while looking at some of my datalogs today that with a MAP tune, the speedo indicates 3mph higher than what the datalog shows. For instance, I had the cruise control set at 80mph, but the speed indicated on the datalog is 77 mph. This doesn't happen with the stock calibration. Why is that?
