J,

The dial for boost you were referring to in your previous post is called a adjustable boost control. They were added by owners or tuners to allow raising the boost level from the cockpit of the car. Better known here as the dial of death.
The factory installed adjustable boost controls went on factory racing turbo only.

The dial of death was so named because it is the fastest way to cause detonation, break rings, melt pistons, and destroy motors known to man. The waste gate boost spring, which controls boost level, is typically .8 bar from the factory. That is the max. boost level the factory considers safe for a 3.3L Turbo motor. Any boost level above the factory.8 bar should NEVER be used without proper engine modifications to support that higher boost level.

With several thousand dollars of engine modifications higher boost levels can be run safely but an electronic boost controller should be used in conjunction with the modifications to do it safely.
