You didnt get the car tuned after swaping the turbo to a bigger one?[/QUOTE]

Power FC is what I used. Never dyno'd, but I used FC Datalogit to dial in settings for my injectors and boost control module. Took me a long time to tune it (with help from a friend), but my AFR were safe and that was enough to keep me from blowing up. The thing I found odd was that the boost was set @ 10PSI when I bought the car from the lemon lot. I had no idea until I installed my gauge setup. Once I changed out turbos and installed the power FC, I kept the same boost level. The car was a beast compaired to how I purchased it. This was on a CA18DET equipped S13 Fastback (European model). 
So if you are asking me if I had my car professionally tuned, the answer is no. Would I do it once I turbo the NISMO, hell yeah. Too many electronics and algorythms at work in a Z ECU. The CA was simple, which is why I loved it.
