ok i was talking to someone and something was mentioned about a bolt on that goes before the throttle body, not like a tornado pos but some kind of bolt on i guess,not a throttle body. Anyways he has a vette so i was wondering if anyone knew what he was talking about.

 

He's probably refering to an "airfoil." I'm not sure what kind of HP gains they get you, I'm curious to find out myself.

here's a link

The air foil is worth a couple of horses, not enough to notice the difference.
