Can somebody let me know, what kind of gas mileage they get with their KA-T?

Going to all depend on how you drive and what the setup/tune is.

I've heard everywhere from 15mpg-30mpg.I really can't imagine 30mpg though.I can't even get 22mpg N/A.

Under normal driving circumstances turbo cars usually will get BETTER gas mileage than N/A anyway. When not in heavy boost turbos are still prob helping to atomize the fuel.

I averaged about 15 mpg with a T04B when I had the S14.

Wrong. Turbos are always a restriction in the exhaust. And under normal driving conditions, there is not going to be enough positive pressure in the intake to overcome the restriction to flow that the turbine is to the exhaust.

As for atomizing fuel, a turbo doesn't assist with that. Fuel is delivered well after a turbo compresses the air. And the primary factor for atomizing fuel is during the compression cycle in the cylinder as heat energy from the compression cycle becomes readily available to help to atomize the fuel. There may be some indirect atomization that occurs when boosting as there will be a little more heat and density in the air the fuel is being injected into, but under lighter loads (i.e. no boost), there isn't any significant difference in the density or heat in the intake tract over an NA motor.
