Guys-do please read the side bar topics on the site link.They criticize the other after market companies for all those short comings and what they have done to address them including replacement parts that are off the shelf items at local parts stores.They also say that most companies send a base program that surely falls short of day to day driving conditions needing programing by the end user.Where the end user ends up with a lap top on the passenger seat for those changes and their set-up with the air cleaner sensor does make those changes all by it's self.They are saying it truly is a plug and play system not needing any programing.

So please do take a second look at the link and it's as I said side bar topics like why their system,how it works,etc.

Thank You
