This has always been a grey area that the EPA has taken a sterner look at recently, hence SEMA fighting back with the RPM Act.
The EPA's position is that a device which defeats or violates emissions controls in a production car is illegal even if the part is only intended to be used in a race car. To put a finer point on it, the EPA does not believe that the use case of building a race car from a production car justifies the existence of parts that can be used to break the law in a production car.
This is a huge change of mindset that's taken place slowly over the past 5 years or so. It started with the diesel tuners since, whatever your stand on the issue, coal rollers were causing lots of quality of life complaints, a lot of "can't the EPA do more about this?" Hence also why companies that make piggybacks and plug'n'play tunes have been the first to get hit in the gas engine tuner world.
