[QUOTE="2011 gtcs, post: 16354526, member: 121478"] Is it setting a DCT or are they sniffing the tailpipe? They usually dont do that with OBD2 cars. Either way if you're getting high NOX I would probably start with replacing the front 02 sensors as well, cleaning the MAF and if anything mix some E85 into the tank, high NOX comes from high combustion temperatures, mix maybe 1 gallon in when you fill up.
