cumminonya, no offense, but you are starting to sound like a dealer ! If claim as such, please state the references and proof. I am always for proof. ODBII port is not for local government and dealer use only, its a universal diagnostic port mandated for common uniform diagnostics. There is NO laws and/or claims that states you can not use it. There is no restrictions for diagnostics units to attach to it. This battle has been fought many times over and won in favor of the people. There are restrictions in changing maps in the ECU, dealers and/or Chrysler can void on that. You as the owner of the vehicle can deny right of usage of the port to anyone. According to this, any non-chrysler dealer using the port will void the warranty .....
BTW, modifying your air intake is a void pending your local dealer and/or Chrysler corporate office decision. There already have been warranty issues and claims denied because of this. Do not trust what you read in the magazines.
