GIAC is a software engineering company with 17 years experience tuning cars. They are known for creating “factory smooth” performance software with exceptional power and reliability. GIAC 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.

GIAC has been producing the highest quality performance software for Audi ® and VW ® performance applications for longer than most other tuners in the market today have been in existence. In fact they have been working on these applications for over 17 years now and have achieved success with these cars year after year because they have been willing to devote the time necessary to get it right. GIAC has a variety of programs for almost every Volkswagen made from 1991 to present and most Audi cars from 1996 and later. All software performance programs feature full recalibration for all driving conditions, which GIAC replicates at their test facility in Irvine CA.
