Got my 4.10 gears-now what?
Just picked up some 4.10 gears for my otherwise stock 2013. I wont put them in until the snow melts. Am I right to understand I now need to take it to Ford and have them change the speedo reading, or can I get a tune and do that? The local dealer will charge around $100.00 but isnt that money I could put into a tune? Thanks for any help.
