[QUOTE="forcefedjunkie, post: 15765629, member: 11105"] The stock tune was put back in last spring, unmarried the xcal. Once they put the new PCM in it would definitely have had a factory cal. Whether or not the O2 monitor would have passed with new PCM is unknown since it now is throwing a CEL for misfires which is never had before. Dealer says these are false misfire readings. Old pcm going back soon. With weather gone to sh*t there is no hurry since car cannot be driven until roads are clear of salt. Regarding 3.73's, there is no correction for them at this time. [/QUOTE]
