Compression is compression.

If you don't have it static, you create it dynamically with the turbo.

a 10:1 motor on 9 PSI is the same thing as an 8.5:1 motor on 12 PSI.*

If you manage charge temps and fueling/ignition correctly, a high-compression motor with less boost will run circles around a low-compression motor with more boost at the same power levels because the off boost and throttle transition areas with be faster.

*(very, very, very rough and inaccurate exaggerated example, of course)
