I have a 06 ram 1500 hemi and I did the DCX gas update but it messes up my pcm and now my tuner thinks it has a tune on it and now I can't restore factory tune or use a different crom. Tuner may need to be reset.

If you just updated your tuner to the 1r13h dcx crom file DO NOT use that to tune your truck, redownload the 1r13 mega crom to your tuner , then plug it into your truck, select vehicle, and you should not have any issues.
