STAGE 3 TUNE OPTIONS

iE offers two levels of hybrid turbo upgrades. Stage 3 is designed for pump gas fuels on all stock fueling hardware, essentially this is a Stage 2 hardware plus hybrid turbo setup. Stage 3 Plus goes all out with fueling upgrades to maximize power on ethanol and TrueFlex. Each level delivers more fuel and offers increasingly higher power output. Use the slider below to explore Stage 3 options and the additional hardware required for each.

STAGE 3

iE Stage 3 offers an easy upgrade into hybrid turbo power levels on pump fuel (91 & 93 octanes) with only the turbocharger upgrade and stage 2 hardware (intake, turbo inlet, intercooler, & downpipe). This setup delivers deceivingly fast performance without additional fueling upgrades.

SUPPORTED HYBRID TURBOS

iE engineers and calibrators valued fast boost response, top-end power, and a robust build when selecting a supported turbocharger as the base for our Stage 3 tuning. After extensive research and testing, we found the best hybrid turbo options that offer a unique combination of big top-end power and responsive boost with very minimal lag, all wrapped up in an easy direct bolt-in install. Combined with IE's calibration strategies, the result is a perfect marriage of modern vehicle tech and raw chest-pounding performance. Turbo sold separately

STAGE 3 TRANSMISSION TUNE

iE Stage 3 and Stage 3 Plus far exceed the factory set transmission torque limit and requires a complete matching transmission control unit (TCU) calibration. IE's matching Stage 3 TCU tune fully harmonizes the complete drivetrain for the hybrid turbo characteristics with optimized shift points, further increased RPM limits, faster shift speed, user-selectable launch control, new drive-mapping, and more.

Stage 3 TCU Tune is a free upgrade from Stage 2 TCU

Important Notice: 2021-2024 (B9.5) model years have limited TCU tune support. Some transmissions are equipped with advanced security locks and cannot be unlocked for tuning. Before purchasing a Stage 2 or 3 TCU tune for these model years, please follow our easy step-by-step Audi B9.5 TCU Unlock Guide using your iE POWERlink Suite App.

EXPLORE THE DEVELOPMENT

REAL WORLD TESTING

At every stage of tune development, the results were dyno tested, street verified, pushed on the track, and expanded to a beta testing community. This verification process provides a library of data from various vehicles, fuels, climates, weather conditions, and altitudes, all used to make numerous changes to the files to maximize performance, driving characteristics, and reliability in any situation. In one of these track tests, an early TTE710 (smaller turbo) tune variant set the B9 3.0T world record and became the official first B9 3.0T in the 9s!

ENGINE MANAGEMENT

Stage 3 horsepower is a serious amount of power for any engine. To keep the stock engine internals safe under these extreme power levels, iE calibration and software engineers employed highly advanced tuning practices and equipment to develop a complete ground-up engine management system within the factory ECU. Extensive mapping rework was performed to support the hybrid turbos and verified in thousands of complete powerband pulls in our dyno cells and countless hours of testing every tune iteration on the street and track. All performance calibrations and safety coding has been rewritten and converted to run with the substantial power gains from the large hybrid turbocharger.

ADVANCED R&D

To properly configure the ECU, iE's engineers installed a variety of additional sensors and probes throughout the engine to record critical data that is not available via the factory equipment. This is an expensive and tedious process; however, the information gathered is priceless when calibrating the ECU for the new hardware specifications. The added sensors record cylinder pressures, EGT, exhaust pressure, mass airflow, and more for a high-resolution log of important turbo and engine operating parameters.

MAPPING STRATEGY

The advanced software development strategies provide the confidence to responsibly build a calibration suite for peak power output without relying on risky modeled information or guesses for engine and drivetrain safety. Hundreds of maps have been defined and calibrated from a ground-up approach to create a fully rounded software suite designed to deliver professional motorsport quality performance while improving everyday driving characteristics beyond factory programming. The result is more than adjusted stock tune mapping and delivers a true large turbo engine management system completely realized within the factory ECU.

COMPRESSOR EFFECIENCY

One of the countless important examples of this advanced programming is the development of the factory wastegate/boost pressure control mapping. The MG1 ECU contains a sophisticated model with many inputs used to ensure proper engine safety adaptations for any operating condition or climate; the compressor efficiency of the larger turbo drastically alters this model. Instead of tuning around these shortcomings with compromises, iE's calibration team expanded the map structure specifically to each hybrid turbo from the ground up, ensuring proper drivability, perfect boost control, safe boost regulation, and guaranteed consistency in all driving conditions.

WASTEGATE PREDICTED STROKE

The vast difference in wastegate flow and response with the larger turbo options compared to the stock turbo provides another extreme example of a situation where the factory mapping has been completely disregarded and replaced with an entirely new strategy. Significant time has been invested in perfecting every input affecting this system resulting in a map that has taken on an entirely different shape matching the characteristics of the hybrid turbo's boost control. This thorough calibration process is the result of many months but delivers unparalleled power delivery and reliable power at any throttle input beyond even the factory feel.
