Default How safe without EM or tuning?

OK here's the deal i live in LA and i have to travel to get the car tuned. I am upgrading my EJ207 to a bigger turbo and injectors. How far can i go with the upgraded turbo without engine managment? I know i'll have to keep the boost down but how much? is a boost contoller needed? the turbo i plan on going with is an FP Green or Similar. I have been told that the JDM ECU is very advanced and maybe it will ajust to the AFR at a safe level.

Who has done this before?

All info is greatly apprectiated
