At 333HP, many enthusiasts consider the Audi B8 S4 to be a well balanced, fun car to drive. It is a fun car which is loved by thousands enthusiasts. On paper, 333HP sounds like plenty, but in reality the B8 S4 can feel a little lacking. Luckily, Audi’s use of the 3.0L TFSI supercharged engine makes it easy to increase horsepower.

The typical intake, exhaust, and supercharger pulley are great ways to add power, but if you want to capitalize on a tuned or stock S4, you need an ECU tune. With a tune, all the parameters which control how the engine runs are modified. It changes parameters such as ignition timing, air-fuel ratio, rev limiters, speed limiters, etc to make the engine run slightly more aggressive.

Our tuning division, VR Tuned, worked hard to develop a tune which provided lots of extra power without sacrificing reliability. Unlike some other tuning solutions on the market, you can install a VR Tuned ECU flash on your B8 S4 in the comfort of your own garage with the optional DimSport handheld tuning device. With the tune installed, you can expect a 32HP increase on a stock vehicle. With modifications, the power increase will be even greater.

  • Stock Power: 333HP and 325LB-FT
  • Stage 1 Power: 365HP and 365LB-FT
  • Stage 2 Power: 390HP and 380LB-FT
