It will be an illusion. No reason why turning the sound off would affect throttle map.
You’re probably going heavier on the throttle- without realising- because it’s not making as much sound.
Btw the modes change throttle map but available power doesn’t change.
Mode doesn’t change unless you select another
It seems to me as if there is a different throttle map between sport and individual, despite all of the changeable settings in individual being the same as sport the car definitely responds to the pedal more sharply.
I have tried eco and normal but the difference between all of them seems very subtle to me both in terms of throttle and steering weight.
Th car always stays on the same mode unless I change it.
My Mrs has an Alfa Giulietta, and the difference between the normal and dynamic modes on that is massive. Normal feels as if the handbrake has been left on.
