Those are good numbers for a 2001 base. In my experience, there can be a fair amount of difference in hp in cars of same make and year. The shop that did most of my tuning had another 2000 base, like my car, that was much quicker than mine.
Its fun to play with tuning a base boxster, but not very cost efficient. I have done lots of mods to my car and am putting out only about 10 hp more than yours. Chip made the throttle mapping more responsive, exhaust and intake made it sound cool and all the mods gave a little more hp.
I have found that the best way to make my car more responsive is to put on a good set of coilovers to lower it slightly and lighten it up where you can (battery, spare, exhaust, seats if you can afford it).
