Hello, every one I'm new here but I need some help. I have a13 Ram 3500 Dually with a 6.7 Cummins and G56 trans. The truck is completely stock. The truck has a check engine light on for a bad NOX sensor so I don't know how long it could have been on before I noticed the loss of power. I noticed that the truck lost power and the exhaust brake quit working and the most boost it will build is about 8-10 psi. The check engine light is a P003A turbo boost control extending learned limit and P2493 EGR cooler bypass position sensor. Everything I have read says that you may be able to clean the turbo but that may only fix it for a short while.
The other alternative is a new turbo. I would like to go back with the factory turbo at this time and have found several but that is where the confusion comes in. On Diesel Power Products they list one for a 07.5-12 and one for a 07.5-18 with a huge price difference. My question is what is the difference between the two? Can the cheaper of the two be made to work? Is it just a plug that is different or different calibration? Is there any way to make this work or is the only way up buy the one that is almost double the cost? Also is there anywhere better to get a turbo? This one seems a little difficult to find.
Thanks for taking the time to read this and hopefully share some insight into this problem.
