SC is a good way for Porsche to steal our money
The package is not complete without some other stuff and it does not add any Hp in any form.
SC - Timing.
Without Connect+ our only getting the stop watch on the MDF/dash, with connect+ you can create your own track on the PCM.
You can also save your lap times on that track and export it to a computer, pretty neat when your on the track.
Sport+ compared to Sport.
Sport have a quicker respons on the throttel, sport+ have a higher boost all over but the throttel respons is more like normal.
So in a sense Sport feels quicker then Sport+ as long as you dont stay above 4500rpm all the time as on the track.
Sport+ in automatic mode will change gears in the higher region (+4500rpm)
If you have PTV it stiffens up even more in Sport+, i would love to have that in Sport........
And as mention above it changes the engine mounts and also ease off the stability control.
Sport response button.
It does not spool up the turbo as most people think.
When you press it the engine goes in to Sport+, but the rest of the car like dampers, engine mounts, PTV are still in the same mode your using.
So pressing the sport response when your in sport+ does not do anything!
But for quick overtakes it is Great, best is to press it a couple of seconds before your flooring so the boost is up.
