Unlock your S5's hidden potential with G.I.A.C. This world class performance software will give you silky smooth power gains, improved throttle response and better than stock driveability.

4.2L FSI V8 owners can expect an additional 12-18 crank horsepower and 12-18 crank torque. For optimum gains, we recommend pairing this software with our Catback Exhaust system.

A.W.E. Tuning is the largest G.I.A.C. dealer in North America.

Most programming can be installed and returned to you within 24 hours.

A.W.E. Tuning is a primary R&D partner with G.I.A.C., and our feedback and dyno testing is integral in producing the final product.

Not only is full throttle power significantly improved, G.I.A.C. DME software also greatly improves the driveability of the car. G.I.A.C. software retains full OBD2/PSD2 scan tool compliance and will not adapt "back to stock." after a few days of driving like other chips.

Why G.I.A.C.?

1. G.I.A.C. has the most experience of any US tuner reprogramming Bosch Motronic. G.I.A.C. reprograms Audi/VW/Porsche/BMW/Mercedes/Fiat/Citroen destined for both US and German markets.

2. G.I.A.C. only writes ECU software and does not lose R&D time on developing exhausts, suspension, turbo kits, air filters, etc.

3. G.I.A.C. takes a base program from a new ECU (starting in their computer lab, using five dedicated networked computers) and completely disassembles out important functions using extremely complex engineering software. This is the same software used for the development of these ECUs by the manufacturer. When needed, G.I.A.C. emulates in real time with a professional engineering emulator, which allows 6 bit triggering and the ability to capture virtually any event while they run an ECU on a workbench.

4. G.I.A.C. then takes that source code and loads it into G.I.A.C. proprietary software "SHW version 8.02", where they can correctly modify any settings in the ECU. This makes G.I.A.C. different because they do not use commercial chip modifying software which can radically limit the tuning freedom needed to make a factory quality program. With a factory quality product, you will get silky smooth performance with stable power. G.I.A.C. can rewrite the code in SHW to modify anything.

5. G.I.A.C. designs and engineers in house all of their own printed circuit boards for encryption using advanced CAD software. They also write all of their own programs for encryption. This allows G.I.A.C. to get product to market much faster for a large variety of cars. It also protects G.I.A.C. software from increasingly common piracy found in the industry today. G.I.A.C. encrypts all of their chips to protect the cutting edge programming techniques they use.

6. G.I.A.C.'s close ties with Bosch Gmbh ensures that their chips are state of the art.

Why consider anything else?

Please visit the G.I.A.C. homepage for even further information on G.I.A.C. and their state of the art technology. Their success in getting the legendary Porsche 959 to pass Federal emissions standards qualifies them as the industry leader.

Upgrade Policy: We will provide free lifetime upgrades to G.I.A.C. chip users who have purchased the chip directly from us. Upgrades apply to current versions of the same type of chip. There are no upgrade paths for certain chips, such as for larger turbo packages. However, we do have discounts available for all G.I.A.C. chip users when purchasing a complete larger turbo kit from us. Please inquire about discounts or with any questions you may have regarding this policy. Also please note that all G.I.A.C. chips advertised on this site are for US spec vehicles unless stated otherwise.
