boost controler
cuz Audi's rely on their ECU software to control the boost. It reacts based on what boost the ECU is creating based on its fuel mapping.
When you go and manually change it, the ECU cannot compensate. The fuel mapping is static and does not change based on anything you do. So you will run lean. You are adding boost, but not more fuel to the mixture. Some guys have totally melted their spark plug tips by doing that. Some have had them burn off and the leftover of the tip fell into the engine screwed it up royally...That said, some guys have had some luck with manual boost control because they don;t push their limits. But they still run lean (or rich if they turn the boost down too low) and it reduces engine life overall.
Audi's are not like many japanese cars where manual boosting is not harmful.<edited><editID>brrman</editID><editDate>38106.6374652778</editDate></edited>
