Nah, you're right.  I think where things get lost is the real cost:benefit.  Take my 5.7 hemi: Its pretty easy to add a CAI and swap a tune and find 20hp.  Hell you can find 12-15 with the CAI-alone.  
But with the m96 in the boxster, you need to spend large dollars on multiple modifications to see the same sorts of increases.  
On mine, I've done headers, de-cat, by-pass valves, 78mm tb, 987 airbox and intake with the EVO filter and riser , lwfw, udp, and a tune.  Yeah.... add that up in your head.  Haha.  I bet I've found maybe 5HP on top.  (Though I've fattened the curve a bunch).  I haven't had it on a dyno, but I've got a lot of years on the "butt-dyno". 
Why'd I do it then?  
Can't help myself.  I modify, therefore I am.   It's what I do.  It's the bigger part of the fun of an enthusiast-car, to me.  I've got some mods I don't like much, and next year I'll change them. 
I think ya just have to be realistic about what you may find, and to many / most people the cost: benefit to modifying the M96 in the boxster just isn't there.  
Fun fact: i'd probably get more performance increase by going on a diet and dropping 30lbs. Hahaha
