I am looking for information on a DR Performance package, it is a Twister series phase2 installed on a 2001 Dodge Ram 2500 diesel pickupon 5-08-2000. I am the third owner and have no information on what has been installed, the dist.has no knowledge and the manufacture doesnt like to answere the phone. I have had some negative comments on DR Performanne and was hoping someone could tell me what has been done to my truck
