I have a 2014 Eco Diesel. Codes came on. Thanks to reading EcoDieselram.com I got Banks Intake exaust manifold
deleted egr valve Erg cooler dpf filter etc. pipe from turbo back to factory mufflers . tuned ECU . Truck was done 2 months ago & truck runs great. Fuel mileage better than before. No Codes. I did the Intake manifold myself, If you take your time it is worth it. Also to clean your engine after you remove old plastic intake manifold.
