Dont Want Detonation!!!!

hello all!!! well i need some more advice..........i just got the greddy 18g turbo installed......now the main concern is how much boost should i run....... so far i have up pipe,down pipe, exhaust, 255 fuel pump, front mount i/c, greddy e-01 boost control, and the greddy t518z turbo, oh yeah and 1 step colder plug (ngk copper).......im gonna get injectors and e-manage soon and have it tuned at gt motorsports......for the time being, what should i set my Psi at???i dont wanna over do it cuz i hear it tends to run lean above 12 psi.....and dont wanna blow my motor....what do u guys think i can safely boost without having to worry about detonation?? ANY INPUT GREATLY HELPS!!! THANX
