It is absolutely correct about the hybrid BOV. It does as Robertox above said.
As for the GSR, don't worry about the idea of having a BOV controlling the boost rather than a Wastegate. it will cause you grief.
An AFM is an Air Flow Meter. It sits before the turbo and monitors the amount of air going into the motor and relays this back to the cars computer. Another way of monitoring the amount of air going into the engine is by using a Map sensor (I belive it stands for Manifold Absolute Pressure? Although I might be wrong about the A part) and that as it says, monitors the pressure in the manifold. From this the cars computer can work out how much fuel to inject and stuff like that. Your car can use either of these, or both, but it is very unlikely that a car uses both I think. I don't have any idea what your engine would use, but if you don't have an AFM then it's not really an issue not having a plumback BOV.
