So I have a 2014 SHO with PP. I found an older thread about a similar topic, but am not 100% confident on what exatly to do.

The PP includes a 3.16 ratio, but when I plug the i2 in and go to the settings menu that allows the axel ratio to be adjusted, it is showing 2.77. When I bumped it up to 3.16, the speedo was off by A LOT.

I read that "factory gears from ford" means that the setting should not be changed, although it doesnt match what it actually is. Could someone please clarify this for me? I am troubleshooting some weird shifting charicteristics under WOT in addition to this difference in speed so I am thinking they may be related.

Other than this issue, so far the 93 tune makes this thing scream. I love it! (only had the car about a week prior to the tune :drivingbad: )

Thanks in advance!

since they are stock gears, no need to mess with them at all, I would not worry about it.
