Please note that the above parts will work only on FSI engines. You can identify your vehicle as an FSI engine by the presence of an FSI badge on the engine cover. If you have a TSI engine, read more about GIAC flashes for your car here:GIAC Software for the TSI.

The latest generation performance software from GIAC is the new standard.

Silky smooth drivability, with gobs of power everywhere. This software upgrade really gives the nimble A3 a huge kick in the pants with a dyno verified 30+ crank horsepower and 60+ crank torque increase, as measured on our Mustang chassis dyno, on 93 octane pump fuel. See the dyno sheet below!

Programs available:

• Stock Program
• Pump Fuel Performance Program
• 100+ Octane Race Fuel Program
• Security Kill Program (no start)
• Valet Program (30mph speed limiter)
• Privacy Firewall (locks program in place with password)

The above programs can be ordered in any combination you wish. Switching between them can be done via a free laptop based program or via the GIAC Handheld switcher. See the video below for how the Handheld device works.

Special Note: Before modifying your FSI engine, make sure your cars fuel system has been checked and is in proper working order. Please pay special attention to your cam follower as this part has been known to fail on a completely stock car.

For 2.0T FSI owners with an aftermarket High Flow Fuel Pump, GIAC has developed a High Pressure Fuel Pump specific High Output calibration. This new file allows your engine to take advantage of the extra fuel being introduced to the combustion chamber.

The A3 2.0T HPFP File is available as a free upgrade for current GIAC users.

Why GIAC?

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

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

3. GIAC 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, GIAC 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. GIAC then takes that source code and loads it into GIAC proprietary software "SHW version 8.02", where they can correctly modify any settings in the ECU. This makes GIAC 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. GIAC can rewrite the code in SHW to modify anything.

5. GIAC 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 GIAC to get product to market much faster for a large variety of cars. It also protects GIAC software from increasingly common piracy found in the industry today. GIAC encrypts all of their chips to protect the cutting edge programming techniques they use.

6. GIAC's close ties with Bosch Gmbh ensures that their chips are state of the art.

Why consider anything else?

Please visit the GIAC homepage for even further information on GIAC and their state of the art technology. Their recent 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 GIAC 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 GIAC 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 GIAC chips advertised on this site are for US spec vehicles unless stated otherwise.
