Speedometer issues with 410 gears

What's up guys wondering if someone can help me out with this issue I'm having. So I installed 410 gears and now my speedometer reads a lot higher mph. For example I'm going 70 and it reads about 82mph. How can I fix that? I know you change the speedometer gear but which one do we need for the tr3650. Thanks for the help!

Re: Speedometer issues with 410 gears

There's no gear to change. These cars have become old school, but they're not that old school.

That's something you adjust for in the computer. Do you have a flasher?

Ford Racing Speed Dial from LMR is what I did.

Re: Speedometer issues with 410 gears

I do have a set tuner can I do t with that? Ford racing speed dial is that just a direct bolt on and it calibrates on its own or how does that work?

You have to tell it what gears you have. I checked it against a GPS and it is quite accurate.

Your tuner might have left that option open. If they didn't you'll need an updated tune.
