I'm new to all this VAG stuff, so a few quick questions about the names of some parts and what they do. N75 valve - From what I can tell, its just a boost controller? It connects to the actuator to open/close the wastegate? If I went with an aftermarket controller, I could just bypass this? N249 Valve - This can open/close the DV to purge boost at any point? But my car being a 96 won't have one? DV - From what I can tell this means diverter valve? Is this what I would know from the jap scene and a dump valve? Purging boost on closed throttle? I assume recircing it back into the system due to the fact the car is a MAF, not a MAP. Any clarifications would be hugely helpful, Thanks, Ian.
