Does anyone know the facts about how and when the GT's computer will be ok and ready for dynoing? We heard somehow the ecm or pcm doesnt program itself until a certain number of miles have been driven? Never heard of such a thing..... I know the opinions on engine break-in are different with everyone, but this idea that the cars computer might not act normal under WOT until a certain number of miles have hit., is a new one to us. I would think just letting the car run for 20 mins 3 days a week would help seat the rings and break the engine in....while varying rpms... but that wouldnt run up miles on it obviously.... any help would be appreciated... thanks !
