Shift points and adding bigger tires?

[Foreman]

When you add larger tires on your Jeep, did you change the shift points? If so, what programmer did you use?

Thank you

Those programmers do, do that depending on the model that you get. They also make the shift points harder as well. Actually depending on the programmer that you get, it should offer like a eco, standard and sport modes.

Most programmer will have harder shift points when you get into sports mode
