Tuners may make a small difference in performance. The larger gains are from intake and exhaust improvements. Also, just about any increase in power comes at the expense of more fuel. A given amount of fuel has a limited amount of power, so more power means more fuel.

I would mostly agree with you with a minor caveat;
A given amount of fuel has a limited amount of power BUT, modern engines are still not very efficient. The fuel they use has a specific amount of energy but less than 25% of the fuels energy is actually used to propel the vehicle. The other 75%+ is wasted making useless heat and emissions.
Tapping into that wasted energy is where mileage gains are to be found and that's where they have come from in that last several decades.
