GM states it as 6psi sometimes, and 7psi other times, they don't even know, but it should be right around 6.5-7psi. With a 3.4 pulley it is ~12 on an otherwise completely stock car, with mods, it should go down. For instance peak boost on our 2000 SSEi is 11.2, because it has high ratio rocker arms. With headers, it would probably drop to about 9-9.5psi.
