Hey guys, i just bought a 99 s70 GLT for my wife and im confused about a few things:<p>What is the Compressor Boost Valve?(wastegate actuator?)<br>What is the Turbo Control Valve?<br>What ever happened to letting the wastegate do its job?<p><br>I know what they are, just not what they do. If this is the ECUs way of mointoring boost, does this mean that the only way to up the boost is through the computer?<p>Ive done a fair amount of research, but im still confused. Ive dealt with turbo cars my whole life, but theyve always been Japanese. In fact, all my cars are Japanese...<p>Thanks in advance!
