Newbie, so this might be posted elsewhere, put a 2.5 inch leveling kit and changed tires from stock 275 60 20 to 275 65 20 on my 2013 ram 1500 hemi..is there a unit out there to recalibrate speedo/odometer...hypertechs evidently won't work, strangely the odometer seems to be racking up more miles than actual....any info surely appreciated, thx
