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?

diablo has been really easy for me on my 12. i had a bullydog on a ram and was not overly impressed but that was for a 04. im sure they have stepped up their game.
I went to the website for diablo and it doesn't look like there is support for the '13. Did something change from '12 to '13?
