In the world of high-performance German coupes, there are a lot of options. For those who know and love Audi, the S5 is the perfect option. The B9 S5 is more powerful than the older B8 S5, but it lacks the awesome V8 noise the B8 produces. Luckily, squeezing more power from the B8 S5 is easy, since Audi left a decent amount of performance on the table.
The most common way to expose this horsepower is with bolt-on modifications such as intake and exhaust. The OEM ECU tune can’t capitalize on these modifications, but an aftermarket ECU tune can. This is where our tuning division, VR Tuned, comes into play. With our B8 S5 tune, ignition timing, throttle limiters, air/fuel ratios, and other parameters are changed to squeeze every drop of power out that 4.2L V8. The result is an increase of 20+ horsepower and 20+ lb-ft of torque. The tune works great on stock S5s and modified S5s. On top of the power gains, throttle response and fuel economy are greatly improved.
