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?

I used the AEV Procal to make the speedometer and odometer accurate after putting 35s on. Works like a charm, and does some other cool stuff too. I think I will try the Daytime Running Lights function next. Also has steering centering, axle ratio adjustments, extended idle for winching, etc.
