GIAC TUNING SOFTWARE:

GIAC is a software engineering company with 17 years experience tuning cars. We are known for creating "factory smooth" performance software with exceptional power and reliability. Our software replaces the standard software in your car’s engine control unit. It is programmed to adjust ignition timing, fuel delivery, fuel metering, boost settings, rev limiters, and/or speed limiters to optimize performance and, in some applications, fuel economy. Performance-tuned programs are designed to dramatically increase torque and HP without sacrificing smooth drivability. Many programs are also created to accommodate numerous after market performance modifications. 

AWE TUNING  B8 S4 EXHAUST SYSTEM:

AWE exhausts have earned praise from owners and the press alike, due to their unique "Jekyll and Hyde" personality. We spent considerable time and effort during development to achieve remarkable civility when idling and at part throttle cruising, while also producing a war-cry wail when full throttle is applied. AWE exhausts are like bespoke suits: each is hand made utilizing only the finest casing and packing materials, and they command respect without calling unwanted attention to themselves. Sophisticated, refined, and powerful, all at once.

Sound levels from quietest to loudest:

AWE Tuning exhaust with AWE Tuning resonated downpipes (highly recommended for all S-tronic S4s)

AWE Tuning exhaust with factory downpipes

AWE Tuning exhaust with AWE Tuning non-resonated downpipes (recommended only for people who like very loud exhausts)
