Integrated Engineering Product DescriptionIE B8 S4 PERFORMANCE TUNE
IE's motorsport inspired software brings track-ready ECU programming to your Audi S4 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 stages available
- Improved throttle response
- Increased Rev limiter
- Remove Top Speed limiter
- Requires IE DIY Flash Tool
- Easily and quickly tune your car at home
*Power figures were measured at the hub performed on a hub dynamometer, power figures are taken from multiple vehicles. Power gains may differ from advertised as individual vehicles will vary in maintenance, mileage, and conditions. HP=horsepower, TQ= Torque ft-lbs.
IE STAGE 1
The IE Stage 1 B8 S4 3.0T tune delivers an aggressive power upgrade without having to install any hardware modifications. Perfect for customers looking for a big jump in power without adding any additional hardware. In a matter of minutes, the vehicle will be much more enjoyable to drive with a massive boost in performance. Designed for use with regular pump 91/93 octane resulting in an instant +45-55HP & +40-50TQ gain.
IE STAGE 2 SINGLE PULLEY
The IE Stage 2 Tune for B8 & B8.5 S4 recalibrates the ECU to take advantage of a smaller diameter supercharger pulley. This faster supercharger speed allows more airflow and higher boost pressures. The result is a powerful engine with a significant increase in power and torque across the rev range. Bottom end torque especially is increased. Files are available from American 91 octane up to Sunoco GT260+ 104 Octane Unleaded. A heat exchanger upgrade is recommended at this stage, but not required.
IE STAGE 2 DUAL PULLEY
Ready to unleash serious power? IE's Stage 2 Double Pulley ECU calibration is for owners running both the smaller supercharger charger pulley along with an additional larger crank pulley. These two pulley's combined create the optimal supercharger ratio resulting in up to 534HP and 520TQ! Available in 91, 93, 100, and 104 octanes along with a specialty E40 (pump plus E85 mixed) blend. A heat exchanger is required for this modification. If you intend to use the E40 blend, a high-pressure fuel pump upgrade is also required. IE's pump fuel 91/93 tunes are specially calibrated with safe air to fuel mixtures which inhibit "knocking". These mixtures also provide cooler exhaust gas temperature and thus are safer for the 3.0T's fragile catalytic converters then many competition tunes.
E40 ETHANOL FUEL BLEND (DUAL PULLEY & ABOVE)
The IE Stage 2 Dual Pulley Tune offers you tons of power potential on multiple octanes options including support for E40. The S4 B8/B8.5 factory fuel system cannot safely support the amount of fuel needed for full E85 even with an HPFP upgrade, however, it can support a maximum blend of ethanol to E40. E40 is an ethanol mix of E85 with regular pump 91/93 fuel (about 2/5ths E85 and 3/5ths 91/93 with E10 premium gas). To run this fuel safely, it must be pre-mixed and verified before filling into an empty tank. You can read our blog article on how to safely blend ethanol HERE.
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. TECHNICAL FEATURES
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
The Audi 3.0T engine continues to make power beyond the factory rev limiter, especially when power adders such as upgraded pullies are added. Our files allow the engine to access all of that power by increasing the rev limiter. Requires matching IE DSG /transmission calibration on S-Tronic Cars.
- Stage 1 RPM limit: 7200 RPM*
- Stage 2 single & dual pulley limit: 7350 RPM*
- *DSG Calibration will shift slightly before these cutoffs
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.
