New 99 Boxster Owner, loss of engine power?

[SVT Cobra]

Hi all,

I just picked up a 99 porsche boxster with a porsche rebuilt certified engine and about 25k on it. I sold my 2.8 1997 Z3 to get it, and I thought for sure the boxster would be faster. The fact of the matter is, the boxster fees about HALF as fast as the Z3. Im sure there is something wrong, but it takes forever to accelerate. The engine runs great, and seems better on the highway, however. It seems as if it takes the gears forever to wind out, the car feels as if it has a 2.82 gear ratio. Is this how boxsters are, or is there something wrong with the car? Any owners near the cleveland area that have a spare moment, Id love to set up a test drive to see if there are any other issues as well, as I've never owned one of these cars (or know anyone that has,) and have no clue what to expect.

Thanks guys!
