Hey everyone, I just got some Pro 5.0 4.10 gears installed in my car. So I took my SCT livewire to adjust the gear ratio. After changing the ratio to 4.10 in my user adjustments, my speedometer is still way off. It is like the ECU is not taking my new adjustment... I have tried adjusting a few different tunes (even the stock SCT tune) I have had no luck... I have tried every gear ratio from 3.08-4.56, and there is no difference in my speedometer. I had my Girl Friend drive beside me and while she was going 55 MPH my car was saying I was going 73 MPH. I have the most current firmware and updates for the Livewire. Has anyone else had this problem?
I appreciate any help I can get.
