I talked to my dealer the other day about tuning and my warranty and they said that they will look the other way if I return the ECU to stock before I bring my car in for service. The service guy also gave me a recommendation of Alternative Auto Performance for my tune. Heres a link http://www.alternativeauto.com/Home.html. Anyone have experience with them? They seem like their geared more toward mustangs but from reading everything about his attention to detail I think he could make a good tune. If I didn't go with his tune I would most likely go back to my original plan of LMS tuning since I live in the area. What are your thoughts on Alternative Auto?
