[QUOTE="JustDennis, post: 1493379, member: 41299"] Update... I took Friday off last week and drove 1.5 hours to the Dyno shop that tuned the truck. After this adventure with the codes, I found I have the MagnaFlow Cat-Back Exhaust System MF Series 3" Dual Split Rear Exit Black With 5" Tips, Whipple Large Mega Cooler and CAI, Stainless Works catted Down pipes and a full dyno tune by a very reputable shop in the Carolinas. Everything seems to be working well. The Dyno shop could see where the dealer updated the shifting via the TSB to the 2018 shift programming and they put my tune back. Truck performs extremely well and the dyno numbers look really good. I don't chase numbers but this truck performs extremely well. Thanks for all the help understanding what was going on with my truck. [/QUOTE]
