ill break it down more simple for the retarded
air goes in at atmospheric pressure (14.7psi)
turbo compresses it 6 more psi (20.7psi)
then s/c compresses it again at(20.7psi)
now what should the pressure be even thought both syatems are only at 6psi. tell me that sir

Does the SC add 6 psi (PR of 26.7:20.7 = 1.3) which winds up being 12psig, or is it running at a PR that gives it 6psi over ambient like I laid out before that gives you 14.45psig.

Either way, you can't just add 20.7psi + 20.7psi, and one or way or another, the flow of the engine and the WG definitely comes into play for the SC and the turbo respectively.

so why again would it be inefficient.

I think you would have connected the dots by now, apparently not. Blowers aren't very efficient at 20.7psi.
