How do you know if turbo is activated? Is it automatically at 3000 rpm?

The turbo is always spinning, as far as how early it starts producing noticeable boost, no idea. The motor feels pretty linear to me so I couldn't wager a guess as to what the boost curve looks like.

The turbo needs enough gas volume/velocity to produce maximum boost, not some electronic activation, so below ~2000 rpm there is little gas volume/velocity and little boost produced. Without a boost gauge you don’t know the amount being produced at any engine rpm/load. I have an OBD tool which shows real-time boost pressure, and total boost depends on rpm, throttle opening and load. I usually see full boost (~10 psi) before 3000 rpm at WOT.
