I have a 2012 JKUR I got used with a few upgrades and have done many since. I do not know if it has had any programming done prior and was looking at getting a Tuner for it to do the tires, ratios, and various other programming. Any recommendations on what people have used. I have also heard the pcm needs to be unlocked, or are there programmer that do this for you as well I used to tune Hondas when I was in that scene but went this way which is more fun
