it kinda kepends on what ECU unit you have installed in your car, Two good tuners are Mikes Dyno Tuning in Dandenong an Rajab Racing Developments, Alan is a genuis at tuning Motecs
mate took his car to one of the mentioned tuners above *ahem to tune his vl upto 20psi and kept pingin out at 15, so he was wondering wtf was wrong till he took it to his other mechanic only to find out they had put the wrong spark plugs in and were burning wayyyy too hot, coulda blown his motor. lucky
Mate hate to break it to you but there is nothing you can "tune" with a stock ECU. The only thing the dyno will do is give you a power reading. So if you want to know what power its making get it dynoed for a power run anywhere.
Onwizz, are you sure the car wasn't leaning out mate thats why the plugs were hot???
How far are you willing to travel...
Depends how much your willing to pay.. Not everyone is the same price...

Everyone has different places to goto but at the end of the day it comes down to who you want to take the car too and who you feel happy going too.. We can only give advice...
Best of luck to who ever you goto...
