My apologies, DeerHunter... you came across a bit strong initially. I do understand your take and stance on deactivation. It's more of an aesthetic preference to go aftermarket exhaust in most cases, all about the glorious sound of the this wonderful v8 coming through. This is especially true in my case, the car is being modified and showcased as part of a local tune shop package offering, kinda joint venture thing. Hence the primary emphasis is on performance and sound, with a dash of practicality with the already ample refinement.

Which brings up another good question... Anyone know if the APR TCM tune for the DSG has any affect on cyl deactivation? I've heard both ways, would like to get it from the horse's mouth if someone doesn't mind verifying.

I can't guarantee that this will disable cylinder deactivation as I don't have an S6 myself, but it is the only way to have the engine in Dynamic mode while in M. If the transmission is in D before you go to M, then the engine is not in Dynamic mode. M simply overrides the automatic shifting in your current mode. It's not a third mode or something, so D->M is different from S->M. In the latter you'll have the dynamic throttle map, faster clutch engagements and faster shifts, while with the former everything remains more relaxed and the engine is in Comfort/Auto mode.

FWIW cylinder deactivation is still active in Full Dynamic mode S or M. It just may be less noticed since you are either typically driving more aggressively in those modes or you're above 3500 RPM...in either case cylinder deactivation is inactive.
Straight from self study guide "The system is also operational in the S-mode of the automatic transmission and in the “dynamic” map of Audi drive select."
Also TCU tune does not change cylinder deactivation in any way.

I recently test drove a new 2016 S6 and a used used A8L with the 4.0T. Most of the driving was on back roads with the transmission in S, and I probably didn't get into four cylinder mode much, if at all. I will pay more attention to that feature if I follow up with these vehicles, which isn't likely. I am probably predisposed to dislike COD because I love the feel of the NA V8 in my 2007 A8.
I was extremely put off by the information that stop/start will be permanent beginning in 2017, and also by the extreme low speed throttle lag on the new S6. The throttle lag was so bad that I commented to the salesman that the car must not have been driven much because it almost stalled. It took a while for it to dawn on me that this was simply the throttle lag issue.
Anyway, although I otherwise really liked the driving dynamics of the S6, and it was better than the long wheel base A8 I drove, I've decided that I am just going to keep my ten year old A8 indefinitely. I'm starting to think that we have reached the automotive high water mark--I don't know exactly where--and that the gas mileage driven features are taking cars down a path I'm not excited about.
Fortunately, my fleet may be adequate to enable me to run out the clock.
