"If your looking for a big boost in HP then this isn't for you but it will make the driveability better by adjusting the shift points and timing giving a little better acceleration. It's worth the money to ring out a little more out of the 3.8 v6." —James T from Woodstock, IL bought a Jet Performance Module for a 2009 Jeep Wrangler.
"Can really tell a difference on the power side. Still waiting to evaluate fuel efficiency though. Pulled a trailer load of firewood with my 6 cyl and could barely tell it was there." —Ricky R from Pollock, LA bought a Jet Performance Module for a 2009 Jeep Wrangler.
"I put it in my 2009 Jeep Unlimited Sahara and VOOM! instantly more pep off the line. I always was disapointed in the performance while merging onto the freeway etc. Now it moves! Also I went from 15-16 MPG on the freeway to almost 20MPG. Great buy ! I went out and got some more Jet Performance stuff to install and improve performance. It is super easy to install too. Took my 10 minutes. I had a couple questions and the Jet Performance tech support was easy to get a hold of and very helpful." —Ryan D from Irvine, CA bought a Jet Performance Module for a 2009 Jeep Wrangler.
