Turn your sporty Audi S4 or S5 into an all-out street monster with IE's complete Dual Pulley ratio kit for B8/B8.5 3.0T supercharged engines with manual transmission.  Get the most out of your 3.0T supercharged engine delivering a massive jump in power up to 548bhp & 525ft-lbs (with additional hardware). This kit includes a dual pulley ratio 207mm crank pulley, IE POWERlink OBD tool, DSG transmission tune, and ECU tune needed to transform your Audi 3.0T into a true performance machine.

Unleash Your Supercharger

This Audi 3.0T TFSI Power Kit offers a complete all-inclusive power upgrade by combining IE's top-of-the-line performance hardware with the matching IE motorsport-inspired software tunes. You will enjoy the track-ready performance while retaining factory comfort and reliability. At the core of this kit is the IE Powerlink cable, providing an easy interface to upload your new tune and maximize the performance of your 3.0T engine. Boost is increased with a larger-diameter crank pulley modification, when combined with IE software they release a true monster hidden in your bay.

Includes Multiple Octanes

IE's dual pulley tune includes 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. 

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.

Required for vehicles equipped with DSG, a great deal of sportiness is added to the tune while maintaining factory smoothness and drivability. More aggressive launches and faster shifts are guaranteed to put a smile on your face. Also, expect acceleration and 0-60 times to improve dramatically from a larger useable powerband provided by the higher shift points. The purchase of an IE DSG file grants you access to customization of launch points. With several launch points to choose from you can pick what works best for your setup!

Available Launch Control RPMs:

• 3400 RPM
• 3600 RPM
• 3800 RPM
• 4000 RPM

IE 207mm Crank Pulley Upgrade

IE's 207mm crank pulley delivers a 3.2753 supercharger ratio similar to a traditional dual pulley setup that uses a combined smaller 57.5mm supercharger pulley with a larger 188mm crank pulley (3.2695 SC ratio). This pulley allows the use of a dual pulley ECU tune without the need to purchase multiple pulleys and press off/on a new supercharger pulley for a faster and easier installation process.
