I have 2 Challenger rt classic one is a 2011 and the other is a 2012 both have 5.7L engines and manual transmissions. The 2012 I own since it was new. The 2011 has 60,000 miles on it and I just purchased it. I pulled the tunes on both cars and for the most part they are identical except the 2011 has the VVT disabled. Is there any way for me to find out if the 2011 is a factory tune and has anyone seen a factory tune with the VVT disabled.
thank you
