MBCs or manual boost controllers usually only control the opening of the wastegate, which is the safety valve of the turbo system to prevent overboost (garantisabog, so to speak).

and like what otep said, you're not actually at the mercy of the cycle, but more of at the mercy of the turbo size (which is dependent on your needs). after all, a smaller turbo could spool up quick, but doesn't have too much top-end power, and a big turbo could spool up pretty slow, but has the top-end power.

there is also an anti-lag solution in situations where there is no throttle input. fuel is injected into the exhaust manifold itself and ignited, allowing for a combustion which still allows the turbo to keep spooling in its "sweet spot", even if there is no throttle input.



hayyy...yun lang muna, sakit na ulo ko dito sa work. heheh.
