Did a gear swap in a 03 and need to re-cailibrate the speedo. Where can i get this done at?

I used a flash tuner for mine but I don't know who's shop might do that.

I think most flash tuners have it built in, do you have one?

I used a Predator tuner on my old 2004. If you don't have a tune or tuner, you can use this: https://www.americanmuscle.com/ford-...tool-9410.html
