Keep in these are figures at the crank. The baseline on the CARTEC dynamometer MRC Tuning uses shows a slightly underrated 572 horsepower. After the tune, this rises to a total of 713.9 or we can just round it off to 714. Over 700 horsepower with just a tune? That's some serious power potential the RS6 and RS7 are packing under the hood.
With bolt ons and a race gas tune 800+ crank on the stock turbos is well within the realm of possibility. Over a 1000 horsepower with upgraded turbos may even become the norm for these cars. The Audi 4.0 TFSI is simply a beast.
