No to bad, fairly simple

Reviewed By brad j (CHICAGO, IL) Reviewed for a 2008 Jeep Grand Cherokee —6/19/2013 8:46 AM

Updating the tuner online ate up the most time for me. One I don't have a personal non-Apple computer, so I had to do the update on someone elses. The forum with the updates is fairly unclear about which files are the most up to date within the 6 pages of posts. After these initial issues the installation on the actual vehicle was quick and easy. The tuner paired with a CAI seems to yeild a more aggressive vehicle. The code reading/clearing is reason enough to purchase the product.

Jet Performance Module Reviews

2008 Jeep Grand Cherokee 3.7L

Reviewed By Peter D (LITITZ, PA) Reviewed for a 2008 Jeep Grand Cherokee —6/8/2011 6:43 AM

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.
