IE PERFORMANCE TUNING FOR AUDI S4 3.0T SUPERCHARGED (B8 & B8.5)
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.

AVAILABLE TUNES
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.

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.

IE POWERlink DIRECT PORT FLASH TOOL
IE's own in-house developed POWERlink cable gives you the control to unlock your engine’s true potential from your own garage or driveway. Enjoy the freedom to quickly reflash your car’s engine control unit (ECU) or transmission control unit (TCU) with IE’s line of performance tunes. The cable simply plugs into your vehicle’s OBD-2 port delivering instant access to choose different IE Tune stages to match installed hardware, take advantage of different fuel octanes, flash back to stock, perform engine diagnostics, read/clear codes and gather high-quality operating data via logging.

I’m sure George is missing his B8 S4 now more than ever. Congrats guys 👍👍

[scalways]

I wish I would have known this tune was going to be this good. I literally just went stage 2 APR and tuned the TCU. I totally would have gone IE had I known 🤷‍♀️

[quickhandcam]

How much of an increase would it be to run E20 rather than 93? I don't have anything available to me higher than E20 and 93 that's under a hour and a half drive lol.
EDIT: Also, what exhaust is used on this S4? Sounds INSANELY good

[sidam]

Would love to see how they do in a 1/4 mile!

[fastsrtfour]

What else is required to run E-85 etc blends? Will it damage the fuel system? I’ve heard it’s better with newer cars, and I’m thinking of upgrading soon!

[TheUSSproductions]

Stage 3 tune coming any time soon? APR gave up on that i think.

[stephen]

Your website use to have the option for stage 2 tune for S4? Is this a newer version

[Zonda.]

Can someone tell me whats the difference in different company's tunes? say for instance.. IE makes 444BHP from 91 and dual pulley and UNITRONIC makes 493BHP from dual pulley on 93?
(the gas shouldn't make that much of a difference)
