WELCOME TO GIAC
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 cars 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.

We also provide custom tuning services for special projects.

GIAC Philosophy
Tuning is an art. To tune for optimal performance is to tune for a careful combination of speed, strength, and agility that varies as driver tastes vary. GIAC exists to tune cars for the way people like to drive.

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 we have been working on these applications for over 17 years now and have achieved success with these cars year after year because we have been willing to devote the time necessary to get it right. We have 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 we can replicate at our test facility in Irvine CA.
