"Small" is what Zex jets for in their "safe shot" kit. 13-35hp. You are going to need to change plugs, look at the entire fuel system like Brian, mentioned as well as getting the car on a nitrous tune.
outside of that though, 100-150 should be fun!
Some cars, Like the GMC Acadia I had would not turn on the A/C and blow cold air below a certain ambient temperature. Not sure if the Titan does that or now.
Personally, I wouldn't change the tire size for a .5" to 1" difference in height. Anything more than that, I would probably look at dongles and apps to make the change.
I have a JLU on 35's and a JT on 37's. Both Sport S models with hard tops. I am very happy with both of them. The JT tows well, it trails well, it road trips really well (22mpg from Here to TN and back- before 37's)
Sport S models are very capable- You don't NEED a Rubicon unless you are doing some hardcore trails.
I have 3 beofeng's for our Jeep trail rides and events. They work pretty good.
Get the longer/better antenna or you will get a lot of unwanted feedback.
