With the emissions and equipment laws that are in place everywhere, there is a massive market for parts and service that serve to bypass the emission standards in the pursuit of performance. You can set up testing, but the enthusiast with the dyno tuner and the manual boost controller is going to make power and burn the gas anyway... If we're looking for control-ability, consistency of operation, and safety... simplicity is usually the best way to get there.
