Has anyone driven 2 GTSs back to back to feel the difference. Its a heavy car, but its also got a very stiff tune without the PDCC.

Is it worth it? It makes a world of difference on an X5.

Yes I have and yes.

 

yes !!

 

Perhaps,but I am doing just fine without it
After driving 1500 miles in 2 days on my way to California from Florida and quickly changing lanes quite a few times at well above the speed limit,I find my CTT quite stable,sharp and precise.
On another note,I find it a real treat to drive over long distances and very comfy

 

I test drove a Cayenne Turbo back to back back with a Cayenne Turbo S that had PDCC. Definitely worth in the improvement.

 

if it is in the car take it - if it has everything else don't worry.
