Hello Lossr,
Craig Porter Here and I know what you're talking about.I've got a 2003 red SSR and last fall I tried the Superchips pwer tune with NO Success!I've talked to othe guys that have had no problems but I think that something is different in the "03" computer In fact thats what the tech came up with after exhausting all efforts to get this thing to work on my truck.I went through a month of sending it back for program updates and all , finally got a refund and bought a Crane Cams tuner with no problems.
