Forgive me if this has been covered I haven't been able to find anything in searches. Working on a customers 2004 Mustang GT that I just installed 3.73 gears in and I cannot find the gear and tire wizard. I did input the change in the speedometer section in the editor and even changed to correct the revolutions per mile but the speedometer is 9mph high compared to GPS readings. I looked in the scanner based on a video I saw and there is nothing when I hit the button that brought it up on the video. Thanks for any help.
