Never mind the company who's 3.6 sc I already have had for months just convinced me to never buy from them again. Since they are on their 2nd tune on the jku and still can't get it right. I could even live with that, as I understand that the product is new. Even though their test jku is the exact same setup and they claim it's reliability is superior. Anyways what sealed the deal was I have left messages beginning over a month ago via phone and email and have yet to be contacted. Yet when I inquired about purchasing a second sc kit my call was returned within the hour....
