its done in the mappin in the chip.
they map it, with duty % (of the air inj) at every loadin site in the rpm, so basicly need to adj, drive, adj, drive etc.
think its very much like fuelin.( in dutys/rpm)
but i aint a expert on this.

Depends on if the chip still maintains the closed loop boost control or not. Probably not for anything above 28psi.
The air injectors stop air getting to the actuator. The mapping opens and closes these injectors to allow the actuator to "see" boost which in turn, opens the wastegate.
They work in reverse to an amal valve. The amal valve bleeds off boost from the actuator pipe.
