WMichaels, I contacted an Upsolute site a few miles from here and ask about getting my xfire done. My wife of course is concerned with the warranty on the car and any long term "damage" with these changes. I tend to keep vehicles for many years and miles ie: dodge dakota 300k, dodge ram 180k. Do you have any idea or thoughts on this? I may just have to take the chance and find out 10-20 years later. I don't want to hurt my baby (crossfire or wife).
