New cams would only decrease gas mileage if the ECU decided to start sending more fuel to the engine.

I guess this is a possibility if the cams allow the engine to breathe more, leaning out the mixture. Your O2 sensor would pick up the lean mixture and the ECU would try to richen it by adding more fuel.
