And yes you can patent a tune, essentially through a carb exempt number you get through EPA, but 1) VERY expensive 2) puts you in EPAs map, which you kinda DONT want to be on as a tuner lolol
As ‘tuning’ by definition is ‘defeating emissions control devices’ since the OEM tune is considered an emissions control device
