Anyone running a programmer on their 4.0? Thinking about getting one. Just wandering people thoughts and suggestions.

I have an 04 Rubicon 4.0 and use a Superchips Flashpaq on it. Helped a tiny bit on mileage, but made the shift points very smooth. Helped to calibrate the Speedo also with my 33" Nitto.

Thanks for the info. Not really caring about the mileage so much as little more power.

There are much better things you can do for a 4.0 than a programmer.

Give this article a read.

Addressing the gearing is the best way to improve felt power in my opinion, especially if you have added larger tires.

Thanks for the article. I've done gearing already. Guess next step is a header.
