APR - ECU software upgrade
What do you guys think of a Software upgrade for the S8?
APR gives you 471hp and 427ft/lbs but also gains of up to 26hp in some area of the rpm range. It costs $925
APR Audi S8 5.2L V10 FSI - APR ECU Upgrade
Is it worth it?
Is the increase felt?
At what cost... engine lifespan?

I would have to see that engine on a test bench before and after in order to believe.
If it is true I am not sure that it would make noticeable difference. On top of 450 HP you need at least 100 more to feel a real kick. Any improvement on a naturally aspirated engines (assuming that Audi engineers know what they are doing) can come at the consumption price. That one you can fell easily.

I had thought about the APR tune and a Milltek exhaust for my 09'. Turns out I guess I am old now and enjoy the car pretty much as it is, acoustic glass and near quiet interior. Besides, the V10 is enough of a fuel hog, I'd hate to see this thing at 8-9mpg. Yeesh. Good luck if you decide to get it. For me, at this time, I'll give it a pass.

I was suggested the Milltek exhaust also, but I don't like the sound. I like the quieter and deeper S8 sound. Milltek seems great for a sports car, But the S8 is not really a sports car and the stock exhaust suits it perfectly.
I inquired about the software upgrade and they told me the fuel consumption will increase but only at higher revs. When I drive the car conservatively I shouldn't notice a difference. But for $925 I would like to notice a power difference.
I am getting the Carbon deposits cleaned out next week and that should show a significant improvement. I bought the car used with 120K so I have no idea how the intake valves look, nor do I have a reference to know if the performance is lacking. It feels great right but I don't know if it's supposed to be even better!
I'll share the before and after pictures taken of the valves.

Also re APR ECU-upgrade, I stopped at their corp HQ in auburn Alabama on a trip to see my son who is in school there, ( actually to get my s8 back from him lol) and the upgrade was $799 with No guarantee that it would not throw any CEL codes. They typically offer $100 off several times a year on the $799 price. Not sure where $1200 above came from.
Hope that helps
