Is a programmer required?

I have a 2013 manual tranny and plan to install a 3.5" lift and 37" tires over the Memorial Day weekend.

Do I need to order a programmer if I don't change the gearing and have a manual instead of an automatic? If I do need a programmer, I am thinking bully dog GT. can anyone provide details about what programmer to buy and why?

You will need a programmer to adjust for the new tire size if you want the speedo and odometer to read correctly.
