I don't know what modern turbo engines you've seen lately. But they don't have flat boost curves. Neither does the stock n54. Yet somehow the torque curve looks smooth. In fancy talk, that's an example of employing a boost profile that complements the engines VE (fancy talk for pumping efficiency.). Good day.
