That would be a waste. If you want performance, you need to get a wider throttle body. Polishing a throttle body requires removing the material from inside. That material is what makes the butterfly valve sit flush. You would probably end up with the car idling too high. You could try it out, but it's much more effective to buy a bigger throttle body.
