I wouldnt do it if thats all your changing. The benefits would be much greater from chip tuning.
If you were putting in a very radical cam, then you might want to put in a carb, but from your sig says, it would be a waste.

Head to head you might notice some improvement since the efi goes pretty rich at WOT but other then that, it would be a waste of money unless you wanted to use a large displacement motor with rediculous cam in it or something.

Yup. You only have minimal mods and switching to carb would only reduce fuel economy, potential throttle response, and ease of diagnostic ability.
