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.

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.
