Those numbers are fine. Put it on a dynojet to get more easily comparable values -- the OEM cats are indeed holding you back. Get resonated HFC's or TP's and retune.
Search for my username and proven power dyno thread to see lots and lots of details on what to expect in terms of output on a dynojet for that and similar set ups.
EDIT: Wait, in Europe I don't know if there is access to dynojet. Seems like Euro dynamometers are usually rolling road... I would see if you can find data for other Z's (MT or AT) at that particular shop to compare and contrast.
That said, I'm sure your results are in line with everyone else's -- no reason to be disappointed.
