I know very little about this app, but it looks like a tuning and sensor app. You could change the program in your car to vary it for performance, or gas mileage. I remember when you used to be able to openly talk about profiles, but the car companies didn't like that and called that info "proprietary".
I digress.
Anyway, I wanted to say: I don't see how this tool physically removes a catalytic converter. It may change the program to let you run without one, but I think the government should go after Big Wrench. They did it.
