Easy install. If your exact vehicle isn't listed in the manual give them a call..great tech support. Definitely a noticeable increase in acceleration power. I'm very pleased and very glad I purchased the pcm.

I have always wanted a "Performance Module/Chip". Jet is one company that a lot of people seem to talk about. It was easy to install and they said i would notice max performance after 200 mile. I just past that and I do notice a difference. is it worth paying over $200 for? I don't think it is. Not when it comes out to $14 per HP. The install took only 5 min. This chip is small so it is not an eye catcher. best part about it is that if something went wrong on my car i can take it out and take my car to the jeep dealer and they won't know i ever had it.

I purchased two Jet Stage-1 Performance Modules, one for my Hemi powered 2008 Dogde truck and one for my wife's 2008 Jeep Liberty. I have played with cars for over 30 years and pretty much no what I'm doing. The Jet Module for my truck really smoothed out the motor, produced more power and better shifting points. Gas mileage went up 1 mile per gallon. I also put a K&N air filter in it as well as a Jet 180 degree thermostat. When I purchased my wife's Jeep, she complained that it was Lazy off the line. She knew what she was talking about, as she has experienced riding in many of my hot rod 1,000 H/P cars. I installed the Jet Module for her, as well as a K&N filter, and she has been happy ever since. Much better performance. These Jet Modules work, but don't expect a massive change, they were not designed for that. If you want gas mileage, buy a small car. If you want massive H/P, build a $50 thousand dollar 60's/70's hot rod. The Modules do work, to a point. If they didn't, I certainly wouldn't buy them.

My fuel mileage has not changed since installing the JET chip, both city and highway, which is the sole reason I selected this product. The engine does sound a little more throaty (other than chip it is stock) and the acceleration feels improved. It seems to utilize more of the engine's power range, and when I am accelerating reapidly it will now strongly run up to ~5000 rpm before shifting. Overall this product is average.

What a difference

I installed the module in about 15 minutes. Actually, the most difficult part of the installation was resetting the radio stations after disconnecting the battery. The biggest difference I noticed right away is the improved power at low rpm's. I have a manual trans and the difference is really apparent. Overall the chip made a big improvement in power - the car now runs like it should have run from the factory.

Just installed the Jet module in my 2006 Jeep Commander 3.7 V6 about 2 weeks ago to get a little more punch. Not only is any increase in power unnoticeable my gas mileage went from 17.5 to 15.9. My next move is to get the induction system from K & N.
