I dont think thats corect. A restrictive exhaust does the same, simple u just dont make the grunt.
You can bleed excess boost off the intake side. Whether or not this is reliable i would veyr much doubt.
Once the turbo compressor aheives the desired boost, the wastegate diaphram pushes open the wastegate. This lets gas bypass the exhaust turbine, so that the compressor can't generate more boost. If you don't have this, (Unless the turbo is quite small, and very accurately sized to the engine) the turbo will continue to generate higher boost levels. This will cause the motor to sh1t itself.
Motors with BIG turbo's need to run an external wastegate, to allow enough gas to bypass the exhaust turbine that the boost wont creep up.
