I've learned a lot from this forum so thanks guys!
Here's a single data point that may be of use - I had the Stage I kit installed by Protosport in 2001 with no intercooler, and here it's 2013 and my 911 still runs trouble free without even a hiccup. A picture can be found in my garage profile section.
I'm thinking that I want more go juice to keep up with the newer 911s every once in a while but then I am reminded just how trouble free mine has been for so long I hate to mess with it! So maybe an intercooler in the future, but for now I'm just enjoying it.
