my dealer is awesome, initially told him when I bought it that i'd be lifting it and if i'd have any issues, he told me if i give him all my warranty work, no problems whatsoever. but he own's a tuned viper and supercharged challenger that he leaves on the showroom floor so he understands how boys and their toys are. we just chatted about warrantying a fully deleted cummins and he said he'd take care of me, so find a good dealer!
