OE Tuning B6 Audi S4 tuning results with Fast Intentions exhaust - + 23 all wheel horsepower
The B6 S4 with the 4.2 V8 is a great car but has never been really considered a powerhouse. Due the drivetrain losses from the all wheel drive the dyno numbers at the wheels are somewhat low for the class leading owners to seek more power. OE Tuning recently dyno tuned a B6 S4 with a Fast Intentions exhaust getting some impressive gains. The max baseline was 253 horsepower and 235 torque to the wheels and the peak values after the tune were 269 horsepower and 265 torque with a gain of 23 wheel horsepower at 7200 rpm. Great results on a naturally aspirated motor difficult to extract power from.
