1. A method of achieving a desired firing temperature of a gas turbine engine during air injection, comprising:
preprogramming into a controller of said gas turbine engine a constant associated with air injection;
injecting compressed air into said gas turbine engine using an external source;
using said controller to:
determine an air injection exhaust bias gain using each of said constant and an inlet temperature of said gas turbine engine;
calculate, based on said air injection exhaust bias gain and a flow rate of said compressed air, an air injection exhaust curve bias; and
operating said gas turbine engine along said air injection exhaust curve bias to achieve said desired firing temperature during air injection.
