Welcome to the board!

I really doubt you're experience "good gains in throttle response and driveability" from an intake mod. Boring out the throttle body is also not going to make much of a difference on a stock motor.
However, a good chip can yield good gains in throttle response and driveability and a little extra HP too.

BTW: The search function is very helpful for finding information on this board.
The search button is near the upper right corner of this page. Do a search for subject "chip" user ID "SteveW". The old posts are a gold mine of information.
