Do I have to reprogram the gear ratio? So the jeep know that I have new gear? From 3.10 ratio to 4.56 ratio

Yes, their flashcal will do it. Tazer is the most popular for this purpose, but there are many options if all you need is speedo calibration.

Tazer will do it, for a few bucks less, J-Scan will do it. Both ways, really easy.
