You think?
If the car has Skyhook, it changes the suspension settings and the sound from the exhaust fakery.
If the car doesn't have Skyhook, it just changes the sound from the exhaust fakery.
I'm 99.999% certain it doesn't change the gearbox settings, other than the change point being slightly higher. Willing to bet if you put it to the test against a stopwatch there's no difference.
OK, you're the expert as always. I just own the car.
