I think it depends more on how much horsepower/torque the motor can handle. The boost just helps it get there.

Its an iron block it'll take more than a aluminum block will 12lbs is perfect, it has low compression so hit it with everything you can. I have a cammed 5.3 with stock heads that puts down 335hp and 315tq. i know for a fact it can handle more. The real question is can you???
