I read a thread the other day that was started in 2002 right when the Z's were coming out I guess. It was talking about a guy who talked to a nissan tech and how the 2003 models were going to have the ecm programmed so that if there were any mods to it the computer would compensate because it would just think the car is over performing. Does anyone know if its true? If it is, since I have a 2003 Z I'd kinda like to know. Any help with this would be greatly appreciated.
