Default Stock trottle body

What improvement should I expect from porting my stock throttle body? Also, I have heard it is not wise to remove the screen on a DD. Any feedback would be greatly appreciated.

the screen you speak of is in the MAF not the TB, you'll probably not see much more than 5-10 HP with a ported TB

Porting the TB will give you a few horses and will noticeably improve your throttle response. I would leave the MAF screen alone, as there are more good reasons to leave it then to remove it.
