It's called "throttle response"!
Since BMW's don't actually have a mechanical linkage to an actual throttle, how deep you press into your gas pedal can be programed to do more or less.
Dinan programmed the throttle to be linear, meaning it is like a flat ramp, while BMW had it more like an arc.
Nothing is being changed with the engine or the gas pedal, only how it reacts to your input.
