[QUOTE="69b302, post: 10616378, member: 52691"] No problem plugging in with a proper tune. I was told by a reputable tuner, that something like the cat overtemp paramter was diabled to ensure a consistent top end A/F ratio. I melted mine, same as the OP, and question the tuner why. The company that made the cats said it was the tune, and the tuner indicated that much of the cat protection was turned off, by design(more consistent A/F rather then have a cat parameter dictate a/f). A plugged up cat could cause lots of issues so I gutted mine. I have done at least two plug in inspections since without issues. No cats can smell nasty. [/QUOTE]
