I honestly did want to mention that in several events here on the forum including your situation,cause if something went wrong i would of felt real bad,vause back on 10/13 the dealer refashed and reprogrammed the PCM, a buddy of mine which is a senior tech made sure that my car was in stock mode,after finishing the process he said when you go home all you have to do is dump your tune back in,that rewrites the PCM,the vehicle goes through the same programming process regarsless if the dealer does it or you do it with your programmer.
