No its just a smaller throttle rotor, so basically your TB opens up faster since its smaller circumferance. But you cannot adjust it.
Overall i dont think its a bad mod, you cant tighen the cable as fatbooty said, and this mod is small and is something you can actaully feel, it doesnt make your car faster, but gives you better throttle response.
