So the gears were changed to 3.73 I corrected this with the tune and I can only get 3.74 on the tuner. The speedometer is off a good amount. I would say it's off about a good 10 miles per hour. I can sort of deal with this but the miles is more then actual mileage being driven. Has this happened to anyone after a gear change and recalibrate through the tuner? Any ideas what to do next to correct this issue and get the speedo dialed in correctly?
