One exemplary embodiment is a method of controlling a vehicle system including an engine, a transmission, and a control system in operative communication with and structured to control operation of the engine and the transmission. The method determines an operating point of the engine including an engine torque and an engine speed and evaluates a relationship between the operating point and a soft limit on engine torque. The method modifies the soft limit to permit operation outside a boundary of the un-modified soft limit. Modification of the soft limit is constrained by a non-adjustable limit. The operating point of the engine is adjusted to increase engine torque above the boundary of the un-modified soft limit. The method may mitigate a vehicle speed lug event and/or avoid a transmission shift event.
