I have a 2014 gt/cs. My car was in the service job for an oil change the other day. The tech told me that he noticed my car had a tune. He told me to be carful because the 2014's with a tune have been running lean and it burns up cylinder number 7. Has anyone else heard this? I know the 2011-2012 had trouble with the number 8 cylinder.
He was their svt tech. I guess he noticed I had an off-road x-pipe and noticed their wasn't any CEL's on
