correct gear ratio

[Jake D]

I have a 2013 f150 ecoboost and recently got the intune. I loaded the tune yesterday and it doesn't display my correct gear ratio. I have 3.73s and it goes from 3.65 to 3.75. My speedo is off a couple mph as well. I picked 3.75 so maybe that's why it's off. I'm not sure if that affects the speedo or not. Any insight to this would be appreciated.

Have you changed the stock gear ratio? If not, don't change it with the tool. It's only if it has been changed. 2mph is within standards.

No my gears are stock. I didn't know if I should adjust it or not but thanks I will reset that parameter to factory. I guess gear ratios are strategy specific and it's already built into the tune.

Correct it is.
