Nope, here's the deal, (this is a 100% volumetric efficency), a N/A engine pulls in air and compresses it (along with fuel) 10-11-12 (:1) times. When you run boost at 8:1, your commpressing the 6-12 psi 8 times. This would make it seem that you might as well run 3 psi on a cheap setup, but with boost and lower comppresion, the engine isn't working as hard as low boost and higher commpresion.
