An engine control system includes a mean effective pressure (MEP) module, an imbalance module, and a phaser control module. The MEP module determines MEPs for combustion cycles of cylinders, respectively, of an engine. The imbalance module selectively determines whether first and second banks of the cylinders are imbalanced based on the MEPs. When the first and second banks of cylinders are imbalanced, the phaser control module selectively adjusts at least one of: a first phaser of an intake camshaft of the second bank of cylinders; and a second phaser of an exhaust camshaft of the second bank of cylinders.
