^ I will look into that.... But your best bet is to call a tuner close to you and see if they are able. alot of tuners aren't "factory Authorized" tuners. But they are usually more than capable and have tuned that system prior. The term factory authorized is pretty Democratic. It is really based upon location. Basically. if two shops are right next door to eachother, they are not going to liscense both shops. Its more from a retail standpoint. But do some research and I am sure you will find some hyrda tuners in your area...
