1. U mean diverter valve. Technically yes
2. Whatever floats your boat.
3. Stages are quite arbitrary and depends on the company’s “marketing”
To me, Stage 1 is just a map tune.
Stage 2 is stage 1 + supporting hardware like downpipe, Intercooler.
Stage 3 is stages 1+2+ major hardware changes like turbo, injector, engine work
