Hi guys first time posting on here hope you can help… i recently got my 2006 300c srt8 back from the dealership after they replaced my TCM and she was running absolutely great!…. for a couple days… I revved the engine for a friend and it went into limp mode…. after pulling over and restarting the car to get it out of limp mode it now sounds muffled and i have a loss of power…. almost like its in half limp mode. I took it to the dealership and they just old me what i already knew and that was that the car went into limp mode because the rpm's went up to 6700… they couldn't understand that even though its out of the initial limp mode that it doesn't sound the same and i have a loss of power. Any ideas what this problem can be!? its driving me crazy!. Thanks for your help!
