When computing your MPG do you use the odometer in your car or go off the ScanGaugeII? Just discovered that due to non stock tires that I had to adjust the speed on the ScanGauge +2%. I computed the difference and then confirmed it using a GPS and the SG set to KPH. So do I use the mileage from the SG from now on?
