Since everyones been asking...Here is the dynosheet of a stock s4 vs a "tuned" stock S4 (same car)
Even though my car has the dreadful dentist drill sound, I decided to dyno my car with a stock ECU in it and see how much more power we could get out of the stock software. Ahh the sacrifices I make for this community! FYI, my car does have piggy pipes and a custom exhaust that doesn't help for ****. I didn't take it to redline as I didn't want my turbos to blow on the dyno =) I'm not getting bigger snails til next month. Stock software runs damn lean all the way to redline (14:1 AFR for those that care) Anyway here it is...

This is on 91 Octane...tweaks brought AFR down to ~12.9:1 Car feels waaaay better...and I didn't even have to add any boost =) This may seem weird because when you add more fuel you usually want to add more timing, as you can see, its not always true.

Cool! Intresting how the torque and HP curves are the oppisite.
I like how the lowest chipped power is the highest stock power. 
Is it just me, or do our cars seem very detuned from the factory? I don't know of many other cars out there that can get the kind of gains we can with just sofware.
