Throttle Body Upgrade

I have a question—I have a friend who has a G1 who had a stock throttle body and had the ECU flashed and also installed a controller. The combination of the two was dumping too much fuel, way too much fuel. You could smell it. He upgraded the TB to a larger one and the fuel consumption problem went away. It’s getting comparative mpg to my machine now. At one point he was using 40 % more fuel than I was. How did the TB alter this problem? Any insights would be appreciated.
