Product Details


IE Performance Software For Audi RS3 8V & TTRS 8S unlocks your vehicle’s performance potential while enhancing the refined factory feel enthusiasts love. Impressive gains are realized on stock cars as well as Stage 2 cars with upgraded hardware. The software can be installed in minutes from the comfort of your home garage or driveway.

IE Performance Tuning For Audi RS3 8V & TTRS 8S 2.5T

IE’s Performance Tune for RS3 & TTRS packs a punch both in performance gains and in additional features. The end result is not only high performing software but a performance solution that does it safely! IE’s calibration engineers have taken several steps to ensure the smooth and safe operation by maintaining factory safety limits, or “fail safes”, resulting in reliability. As a final step, the software has been calibrated in test environments that ensure smooth operation in all types of climates and elevations.


The IE Stage 1 ECU Tune is precisely calibrated to make the most of your stock Audi RS3 or TTRS. Power gains are delivered smoothly across the entire powerband and many performance features have been added. Enthusiasts will have the choice between several fuel octanes (91, 93, 100, 104) and the ability to flash back to stock within minutes. As another added benefit the IE Stage 1 Tune has been designed to adapt to minor bolt-on modifications, such as an intercooler or intake

1000cc Injectors

E85 requires much more fuel and can stretch the limitations of the factory 2.5T fuel system. IE offers an optional 1000cc injector file included with your tune that allows the installation of larger port injectors. When added to the direct port injectors, the combination allows massive headroom to safely run E85 worry free. Adding larger port injectors is more cost efficient and reliable than an upgraded HPFP and will run on both pump gas and ethanol with a regular idle and stock-like drivability.

E60-E85 Adaptable

Although full E85 is recommended for the highest power output, safeguards are included within the E85 ECU calibration to adjust for ethanol as low as E60. This flexibility gives you the confidence to safely fill up at the pump which can commonly test lower than advertised E85.

Technical Features

Dynometer Optimized

After completely reverse engineering the factory ECU, our engineers use our in-house Dynapack DP42 dynamometer to perform repeated runs to test each change that is made to the software and confirm drivability in any situation. This ensures IE performance software delivers massive horsepower and torque increases across the entire powerband. Using our in-house dyno and advanced tuning tools, IE engineers have fully optimized every aspect of the factory ECU mapping on many different vehicles. This produces a tune that retains all factory like driving and safety protocols when needed, and an intense surge of power when you want it.

Removed Speed Limiter

The factory ECU speed limiter has been removed to make sure the increased power and torque can be used to its full potential on straightaways and drag strips.

Increased Rev Limit

With the significant power increase, the rev limiter is also increased to allow a wider powerband on all IE Audi A3 files. By increasing the rev limit, you gain a perfect match for the increased performance available from your new IE performance software tune.

Improved Throttle Response

To further increase the responsive feel of the car, IE engineers have carefully adjusted the throttle sensitivity. This offers a more connected feeling to your car with plenty of power available right beneath your foot.

Optimized Fueling

All IE tunes have been adjusted to run as economically as possible, dialing in air/fuel ratios to exactly where they need to be. With an IE performance ECU flash, it is common to see increased fuel economy under cruising and part-throttle driving.
