Hello. I have an issue that I need help with. I have a 2015 Ram 1500 ecodiesel with 98,000 miles. I did a complete egr and emission delete and flashed the ecu with a tune for the deletes. I had a very loud screeching noise when I first started the engine. That came from a block off plate that was not sealing. Fuxed that issue but I have the service electronic throttle control message on my dash an low power with no turbo. The only code is a U0102 failure to communicate with TCCM. I do not have 4WD. Any suggestions?
