The kind of shops that copy work from other shops. Just flash what they have already there and go. Since they don't know what it takes to create a really good tune for these vehicles. CopyCats

So 100% need an intake. How about ghost tuning or program switching? I want the extra power and is easy to be got but Im not sure I want to risk my warranty on a car that's already stupid fast. My RS6 has a feature called program switching. A series of inputs on the turn signal controls changes the program from stock to crazy, this is aftermarket by the way. So the tune is 100% hidden from the dealer. They can not see it and no one to date has been burned. Is something like that possible on this platform. or are there other options like spare ecu's or something like that. Would love to hear an informative response.
If you flash the factory ecm in a c7 gm will be able to tell .

Oh man people quoting the full long original post need to be banned. Seriously the first time people are using a forum?
As for the OP, awesome news. Upwards of 700WHP possible for less than 5 grand maybe with headers, tune CAI and off-road X/no cat? Sign me up!

Wait and the M7 cars won't be? 
What you A8 guys gain in shift speed below 120 us M7 guy's gain in having less drive-line loss and more available wheel power and speed above 120.
It will be interesting to note at how much WHP both the A8 and M7 clutches start to slip and if there are any cooling problems.

which is why I'm sitting out this model year and going to wait for all this R&D to play out. With the more aggressive gearing of the A8, it will be interesting to see how extra power is put to the ground in lower gears (0-60).

For a lower level comparison, look at A6 and A8 trap speeds in the C7 vs. M7's.
Acceleration at much over 120 mph, to me, is a useless metric. 60-130 times will be interesting however.

Many tracks have straights that go well above 120 in a car with 650hp.
M7 is a much simpler and direct way to get power to the rear wheels. Torque converter in fluid and wet clutches = wasted power. A M7 will put down more WHP than a A8. The only thing an A8 is more efficient at is shifting speed. The A8 also gets worse gas mileage, and you pay for it. The last facet would be gearing. The lower gearing of the A8's lower gears may mean traction will be more of an issue and harder to control on non-prepped surfaces. That's not even getting into trans cooling issues that would arise first on the A8 before the M7 IMO. Looking forward to real world results.

The only issue that remains for me is the cooling of the A8. With my A6 C7, I wasn't going to put any time into researching and implementing tranny cooling measures because I already had a deposit for a Z06 order. With the Z06, it the trans temps aren't adequate, I'll use whatever measures are available from vendors like LG. Same as a GT-R...with an advanced level driver the tranny will overheat on track and people regularly tracking them have to upgrade the cooling. Those who don't are the cars you see doing cooldown laps halfway through sessions before pitting-in.
I personally wanted the best of both worlds. This car won't be my regular track car. If that ever happens, and the A8 isn't adequate, I'll sell it and move to something else.
