Yes you COULD just keep turning up the boost and it would be way more power than 5-7psi on a higher compression motor, or you could get 10:1 and 10-15psi and be right in the same range, not to mention having a better powerband. Why wait for 20psi when you can get the same power w/ less boost?
Compression ratio has nothing to do with lag. Engine displacement, manifold design and timing affect lag, not compression ratio.
at 10 psi i would just rock the stock pistons and maybe the millenia rods.
