Hi,

has anyone tried the Jet Perfomance chip on their KJ? I would like to know what you think of it?

I am about to install one, but have my doubts if it is worth the money?

A couple of people who use them; there are a few threads on the subject:

There are other threads, just search for jet and chip. Another alternative is getting your pcm flashed. If the jet chip comes up in the thread, usually the B&G flash (http://www.bgperformancepcm.com) does too. They cut the price $100 recently, but its still more expensive than the Jet chip. If your KJ is still under warranty, you would probably want to pick up an extra pcm for the flash so the dealership doesn't give you trouble over it. I went with the flash, and for the most part i'm pleased with it. There is a thread in the 4x2 performance forum about it.
