A system for improving performance of a hybrid vehicle at higher elevations. The system includes a plurality of wheels, an engine, an altitude sensor, a transmission, a memory for storing target engine speeds, and a processor. The engine provides a torque to the plurality of wheels through the transmission, based on gear ratios limited by a wide open throttle (WOT) guard. The altitude sensor determines an elevation of the vehicle. Above a certain threshold elevation, the processor changes the WOT guard to improve performance at lower gears, such as standing start performance.
