In 2003, the Audi S4 with the 4.2l V8 produced 339 horsepower and 302 lb feet of torque. In the same year, the Corvette Z06 with the 5.7l V8 produced 405 horsepower and 400 lb feet of torque, an all aluminum motor that is cam in block with a lower center of gravity compared to the complicated twin overhead cam engine that the S4 uses.
i believe the extra power came from a different intake manifold, tuning and free exhaust flow similar differences between the S6 V8 (340hp) and the A6 4.2 V8. You're pretty much limited to the hp increases in the 4.2 as there isn't much support for it. You can squeeze an extra 20 hp from a chip and an exhaust, just don't expect miracles.
The Audi S6 engine is referred to as the CEUC variant, which is different than the S8 and RS7 models. Look at page 6 of this PDF. It's a great read on the engine.
