I have a JET stage 2 chip from a 2003 Hemi. I was wondering if I could install it in my 2004 Hemi. Anybody have any experience here? Anybody use JET products? My brother took it out of his truck because he thought it created electrical problems. JET recommends a 180 thermostat and aftermarket exhaust for the stage 2 chip which he did not have. Has anyone seen any performance improvements or negative results with a JET chip?

 

It won't work on the '04. The computer program for the '03 is different from the '04. Most of the posts I've seen on this and other boards, are not very fond of Jet products.

 

I uses the stage 2 in my 2000 4.7 Dak and had to repalce my speed sensors twice in my trans at $400 a hit! Have not had a problem since with my trans since removed. The truck did seem fster with the chip but it cost me dearly.

 

The jet chip does show a minor increase. BUT, after about 500 to 800 miles, the computer has adjusted for the chip and you are no longer seeing any gains.

 

Does not even make a good boat anchor. Nuff said.
