Hello everyone, new member here, I have a 12 RT 5.7 and I got the flashing ETC light. I (not my first choice) took it to a dealership and they informed me it was the throttle body (320$ plus another 300 something on labor for four screws?) and possibly the PCM though the PCM will be replaced by Chrysler. Now, I can easily replace the TB myself, my question is will I require a calibration or some sort of tune even if I replace it with a Mopar TB? If so what is the process and can I do it myself? If not how much will the dealership charge me to reflash the PCM? I recently got out of the Army and I’m going to a CDL school next month so I am not trying to spend any money I don’t have to. Thank you for any help or advice

you could probably swap out the TB on yours.

The later years seem to require the re-learn procedure. The '15s changed PCM architecture.
