I no longer have my Jeep and have my Flashpaq 3875 for sale. I loved the tuner and it gave noticeable amount of power as well as increased MPG (I was averaging 20 MPG with my 4.7L V8). It works with tons of Jeeps and it's capabilities vary by Jeep. this site has a compatibility list and if you click the applications tab, it gives the capabilities for each Jeep.

Located in Bennington NH, however I work in Keene and sometimes in Merrimack, so I can meet somewhere.
