Great job on the FWI, I run that exact same thing as does Black97SSEi. Neither of us have added any splash shielding although it would keep the filter cleaner.
The mod bug has him already. Since you are semi local, we should probably plan a meet day. That way some of us that have all the crap (fuel pressure gauge, scan tool, etc etc) can assist you in checking things over before you begin modding.
All you really have to do is holler two words out your door and you'll have a meet. The words are "Meet" and "Beer"... that usually gets the tires chirping. (Just don't aim for this w/e..I need to put my tire chirper back together)
