AVCS = Twin scroll?
Hey mate. No AVCS is variable cam timing. IE different lift during different revs.

Twin scroll is the turbo and headers its self. Twin scroll has 2 gas entry points into the exhaust housing of the turbo instead of one. This is a far more efficient method than the single. Hense why it creates boost quicker and holds it for longer.
