How many miles?

One thing that could be slowing you down are the cats and o2 sensors. They only last about 90-100k miles.

I am at 117k so it’s definitely possible they are original, should I get mopar o2 sensors? Or will any work? Here in California if I need a new cat only shops can do the work from my understanding.. crappy lol

I just put new cats in my 06...a little over 800 from jeep dealer. you can install it yourself. My jeep (06 lj 4.0 6mt) with 4 ppl and camping gear will pull 65 plus (I try not to go faster) up most Hills around here and I've got 35s with 3.73 still. But, 4th gear is used alot. I plan on 4.88 real soon as my front case just wore out anyways...Just got to find someone to do it now

Stick with Mopar sensors, or you will be swapping them out again soon afterward.
