You'll find that an otherwise stock ls3 will make about 525-530 whp at 7psi because it makes about 360whp n/a.
That is the reality, you want more, you increase the static flow or you increase the boost, those are your ONLY options. Bigger turbo will NOT add more than 48% additional airflow at 7 psi of boost. That's pretty much the DEFINITION of boost...

I have 3 friends with LS3s that made 620 at 7psi on a stock motor, stock cam with a D1 blower
