Quick Performance

It woke up this 5.7 HEMI. Throttle response improved along with shifting.

Notice some power Gains

It was easy to install and I have noticed a slight power upgrade. One thing I would note about this unit, is in the instructions it tells you to completely remove the ECM from the unit before installation, however I had a difficult time removing the ECM because of corroded fasteners. So, on my 2006 Jeep TJ SE, I was easily able to install this without removing the ECM from the engine compartment.

I installed the JET Stage 1 Module in my 1995 Jeep Grand Cherokee ZJ 5.2 and I couldn't be happier. Originally, complications forced me to send the chip directly back to JET's warehouse, however I received the chip back in only 4 days (from the day I shipped it, and did I mention they remedied the problem free of charge, excellent customer support)! Once installed, my Jeep drove like nothing I've ever felt, it was responsive and FAST, with great power on all sides of the power spectrum, as advertised. I can safely say that as a company, JET certainly have earned my trust as a customer. Derek

Power, response, and easy install

Very easy to install for anyone! If your vehicle is still under factory warranty, you should remove it before taking to the dealer

Nice Power! More MPG! Better Shifting!

I installed this on a 2001 Jeep Grand Cherokee. 1) The ECM is kind of difficult to remove, you have to move/disconnect 3 harnesses and the computer is mounted to a rack that is difficult to remove. 2) you really have to press the module into the ECM otherwise it will throw codes and the motor will not run correctly(if at all). 3) There is a noticeable difference in shifting, it is quicker to downshift when accelerating and it delays to upshift if you want to step on the gas again. The throttle response is quicker. 4) It will give you better gas mileage as long as you are not flooring it all day long. I was doing 14.3 mpg average before i installed this, then I installed this chip and a CAI and now i am getting 15.3mpg.

Really adjusts power and shift points

This is very easy to install. You can definitely tell improvements in the power and the shifting points. I removed it when I went to the dealer. I could feel the differences right away. The minute I left there, I pulled over and re-installed the chip!

Noticable power improvement

It's a 4 banger, wasn't a huge change in power, but it is noticably better.

Not sure it did anything

I'm not sure this did anything for my 09 Jeep Grand Cherokee. I have to run it a couple hundred miles and do a fuel mileage check. If it made a performance increase its so little you need a dyno to get the results
