None of them add any real "Performance" on our TJ motors. If you find one, let us know.

From what I've read, they work temporarily. The computer interprets the chip as altered performance and adjusts with the chip input to go back to original performance. So, a chip may work for a few days. If you don't mind installing for trail rides only you may be happy with one.

To answer your question none. Sure there might be something out there that just makes your engine run lean, you'll end up paying dearly for that in the long run. If you have a dire need for more power than I would look into a stroker or a Magnum V8 swap.

They don't work on a TJ. No matter what the ads in the magazines say.
