How to reprogram the computer of a 2001 galant

Hello, there are some obd connection cables that are called Galleto that are to make reprogramming. On Ebay you can find them at a good price (an average of € 30), sell the 1260 version that must be of the utlimas. Some vendors include preconfigured maps for many models.
I neither have it nor have I used it so I can not help you more in this aspect nor can I tell you if it is easy, sure,
etc.
