My 2015 Eco has 63K miles and has been a great riding, driving, and great MPG truck. If you look at some of my other post you'll note that I have been plagued with truck throwing CEL and Service Electronic Throttle a few dozen times since 32K miles. The dealership and RAM have been very professional and worked with a sense of urgency to get me back on the road or have given me a rental loaner. All work done has been under warranty and only cost to me has been them dumping a full tank of fuel when they changed injectors and lost time with truck. So far they have replaced the turbo, all six injectors, MAP sensor, air intake pipe and cleaned fuel system and cleaned EGR (twice). They have ordered another MAP sensor as RAM (Star) wants it replaced again. Thought it was fixed as it did not occur for last half year but it came back. Anyone know of any other fixes for Turbo overboost/Turbo underboost ?
