What's the best thing you've down to add power to the 4.0l? I'm not talking a blown hemi or anything so...
- Cold air intake (flow = go, as @custommuffler would say)
- Throttle body spacer (stack 2 or more of these for a real power boost)
- 86-port injectors (basically the more ports the better)

#1. Install 5.13 gears for your 33s. Then worry about more power.
That's next. Im waiting on Barnes for my truss. 5.13 gears ok at 70 mph?
Installing the correct gears for your tire size will make the largest difference. The I6 4.0 is only 190 HP, so it's not a hot rod and will never be 'fast'. The only thing it does that is fast, is drink up all your gas.
Don't forget the best device ever made.

I ran a Kenne Bell Supercharger on my I6 for years. About 300 ponies and 400 torque at the flywheel. Most reliable mill I’ve ever run.

You just need the gears. 513 for a Sport is as deep as you can go without changing axles. Yes, 513 for the 42rle and 33’s. You could also get the wranglerfix pcm tune.
