I was wondering if anyone had troubles when trading in their 6.0 or 6.4 I traded in my 6.0 about a month ago for a new 6.7 About 3 days later the dealer called asking if I had the old parts from my EGR Delete. They were begging for them. Since they treated me good I gave them the old parts. They said they can not sell that truck the way it had been changed. Then they admitted that if they knew it was like that they would not have excepted it as a trade in. They were cluless about the 6.0s reputation. I asked why in the world they would change it back when having a delete in my mind would be a good selling point. In Pennsylvania they can not sell a vehicle legally when emission equipment have been altered even though diesel engines do not need tested.. Well.... Yet..
