Question on Computers

[1996MustangKid]

Hi, I have a 1996 Mustang GT and will be getting 4.10 gears for it, however my question is can I have the computer reflashed to calibrate for the gears? If so, I live in Michigan any ideas on where I could have this done at?

To me it's not worth reflashing just get a Speedcal if you even
do a gear swap.
