An engine control system includes a desired manifold absolute pressure (MAP) module, a MAP to torque module, a threshold determination module, and a fuel economy (FE) mode module. The desired MAP module determines a desired MAP for operation of an engine in one of a cylinder deactivation mode and a low-lift mode based on a difference between a desired vacuum and an air pressure upstream of a throttle valve. The MAP to torque module determines a desired torque output of the engine for operation in the one of the cylinder deactivation mode and the low-lift mode based on the desired MAP. The threshold determination module determines an entry torque based on the desired torque output. The FE mode module selectively triggers operation in the one of the cylinder deactivation mode and the low-lift mode based on a comparison of the entry torque and a torque request.
