> The illegal vehicles had adjustable carburetors that were not described in their application for certification, were produced by a different manufacturer than the one specified in the application, were manufactured prior to the date of the certificate of conformity, had model names that were not identified on the certificate of conformity, or were significantly more powerful than described. The illegal engines were incorrectly certified as non-road engines rather than as recreational vehicles and some were significantly more powerful than described in the allegedly applicable certificate of conformity. The EPA and the U.S. Department of Justice also alleged that the emission control information labels on certain vehicles did not comply with federal regulations, and that Tractor Supply Company provided an incomplete and inaccurate response to EPA’s information request.
> According to the charges, the company's engine software
controls the timing of fuel injection into the combustion

while the truck is running on the open road. However, the
company's engine software is designed in such a way so that these
emission levels do not show up on the federal test.
What do any of these have to do with end users modifying their equipment?
