Kudos !

It was refreshing to have had a great buying experience with Their knowledge and responsiveness to my questions made me very comfortable to choose the SCT X4 for my Superduty Powerstroke. Even though I was shopping for an entry level plug and play tuner, they spent the time to answer my questions and make recommendations based on my specific truck and use. II am very happy with the tuner but happier with the excellent customer service. Free overnight shipping was the icing on the cake. Thanks again!
