Description

IE's motorsport-inspired software brings track-ready ECU programming to your Audi S4 3.0T 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 STAGE 1

The IE Stage 1 B8 & B8.5 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.

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 DOUBLE 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.

EXTENDED RPM RANGE

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
