Ok, here is the skinny on this issue. If you put a chip into a truck, no matter who's, the manufacture, they CAN void your warrenty. It's up to the dealership if they want to report it. DMC I'm sure know what going on and leaves alot of this up to the dealership. So, it's up to the dealership to basicly Narc you out, or not. And if the local rep thinks they need to look into computer, they can. Then you have the problem of being on the open road and having a break down and getting towed to a dealer you don't know.
What to do what to do. It's up to you. ANd if I broke down on the road, it would be the first thing out of my truck after me of course. No need to let them know something and then they don't have to lie to the area rep. Make them work hard to tell you no.
I run a edge chip and love it.
