Anyway, what I like about the amalvalve is the fact that the ecu can lower the boost level if needed (when the ACTs are high for instance). As far as I know the amalvalve is the only boost control that makes this possible. Or are there other possibilities to do so?
Amal valve is simply a valve. Nothing more, nothing less.
How any valve is controlled is what is most important. But obviously a quality valve offers better control
