It will have that effect as boost is mapped against throttle % and rpm.
Throttle plate % will be changed by the S-Drive.
The different S-Drive modes just alter the amount the throttle plate opens Vs the amount you press the pedal. Unlike a conventional cable throttle where it's totally linear (you push the pedal, it pulls a cable and the throttle opens).
For example, in the more sedate modes 10% pedal will give 10% throttle
In the more aggressive modes 10% pedal movement may give 18% throttle.
The disadvantage of the more aggressive modes is that the last 20% of the pedal movement is normally pretty dead.
It makes it feel like the car is quick, but you can get just as much out of it in the lower setting by being heavier on the pedal
It's also mapped 3 dimensionally against RPM, whereas the above just describes the 2D effect.
