In some climates emergency heat, in the form of electric heat strips is installed only to handle a portion of your total heating requirements. You could have dropped strips or you could only have enough to produce the temperature rise you are experiencing. If you are in a climate where outdoor temperature that requires emergency heat is rare this may be the problem. It comes down to design of the system. Usually you can add/change heat strips to ensure capacity while operating in emergency heat mode.

When in emergency heat mode you are only using electric heat without the help of the heatpump when both are running you have the benefit of electric heat and mechanical heat

How cold do you mean by really cold? At 32 degrees, your heat pump can put out a 20 degree rise, so added to 85 degrees, your 107 is pretty close.
Temperature rise for electric heat only can be calculated. All you need to know is how many cubic feet of air you're moving, making sure your filter is clean, and correctly sized ductwork.
