does turbo charging a 4 cylinder engine make the gas mileage get worse?

Yes it does. Even when you are not heavy on the throttle, a turbocharger acts as an exhaust restriction. Even cruising at a constant speed your milage will be slightly lower than without the turbo. But I think you will find that with all that new power, you will be USING it alot. So since you are going to be on the throttle alot more you are going to burn more gas.

Yes. You can calculate fuel consumption and fuel injector usage using the BRSC formula. A turbo car of the same horsepower as a naturally aspirated will have a BRSC value of .6-.65, while the naturally aspirated car will have a BRSC value of .50-.55.

Not much. It depends on how big the turbocharger is. Small turbochargers do not affect the gas mileage.
The Volkswagen GTI uses a small turbocharger and could still get 31mpg with 200HP.
Big turbochargers that bring the power up by more than 50HP do affect the gas mileage. It will only make it worse by 1-5mpg.

No, the efficiency of the motor will increase. The turbos run on waste gases from the motor. If you floor it, then it will eat more gas.

Only if you use the extra power, but why would you charge it if you do not want to use the power!
