Which would you get to give you more power? when they are availible of course. could you essentially use both? would there be any benefit in that? if some one could shed a little thought and knowledge on the topic i would appreciate it

Throttle Body Spacers are useless, they do absolutely nothing to performance on the Hemis. They make great paperweights. I don't know if Fastman has throttle bodies for the 09s yet, but a better throttle body is a good investment, a spacer is a waste of perfectly good money.

That's funny lol, I did see some somewhere but don't remember, but will post if I come across it again

Think of throttle body spacers this way. If the factory could get any meaningfull improvement in HP or mileage with a $5 chunk of aluminum with a hole in it - don't you think they would do it?
