IE's motorsport inspired software brings track-ready ECU programming to your Audi A4 (B8/B8.5) while retaining factory comfort and reliability. Developed in-house, IE engineers are equipped with industry leading tuning technology to completely reverse engineer the factory mapping and safely modify it to maximize performance. Years of professional tuning high-powered race vehicles and intimate knowledge of the VW & Audi engines results in a wicked fast car on the street or the track. Your new software tune is easily uploaded to your factory installed ECU (engine control module) without touching a wrench in your own driveway. Multiple tunes are available to match your stock or installed aftermarket hardware.
IE K04 ECU Tune
Ready for more boost? The IE K04 Tune is meticulously designed for bolt-on Borg Warner K04 Turbocharger upgrades and features a completely new ECU calibration to take advantage of the larger turbo efficiency range. Upgrading to a K04 and Tune results in a much wider RPM band and power doesn't taper off like the factory installed K03 turbo. The ECU tune is safely adjusted to take advantage of the larger compressor wheel to reliably release the full potential of the new turbo size, pushing power much higher than available from the stock turbo. Tune includes 91, 93, and 100 octane files for maximum power.

Easy At-Home Tune Install
Required to flash your new tune, IE's DIY Flash Tool allows you to quickly upload your tune from your own garage or driveway. This OBD plug-in device is easy to use with a Windows-powered laptop and WiFi connection. Your new tool also includes the abilities to switch between multiple octane files (available separately), reading and clearing diagnostic codes, upgrading Stages, or flashing back to stock.
Already have an IE Stage 1 tune and IE DIY Flash Tool? Upgrading to Stage 2 or beyond is easy! You only pay the difference in cost between the files with no additional or hidden fees. Once the required supporting hardware is installed, simply plug in your DIY Flash Tool and follow the instructions on your screen to purchase and flash the upgrade file.
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 A4 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.
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.
