I purchased the two stage kit. A highly qualified mechanic installed it. Immediately the check engine light came on. This was a new 2013 Jeep Wrangler. I spent the next six months making calls to the company getting direction on who too see and how the check engine icon could be removed. Nothing worked. I was finally told that the kit would only fit my vehicle when Chrysler released the "protocol' that would allow the cars computer to accept it. Now I called every place I could find to see if the protocol had been released. After no success getting that information I called PCD back and this time I was told that it would be about 18 months before that protocol would be released for this late model. No one told me that at the time of purchase. I eventually cost me over $300.00 to get the problem corrected and the check engine icon removed.
