I have had several Z3's and boxster's , and now on another 911
The boxster is a far better car than the z3 (sorry to say), it's balance , power delivery and poise blows a z3 away and makes it feel antiquated

Handling is definitely more neutral, its very well balanced with masses of grip. grip round corners and grip from a standing start.
Steering is very accurate.

However, there is more scuttle shake, so it will be getting a front and rear strut brace. this may help reduce it a bit

I dont think you'll see much of a gain, maybe 1-2hp. you would notice improved pick-up off the throttle.
Main reason for using underdrive is in a race/high rpm situation so you dont cook the alternator.
