Ready to experience true racecar power without compromising reliability? Continue reading to learn about our innovative and advanced hybrid turbo tunes or the B9 3.0T platform or visit the product page HERE.


IE Stage 3 tunes are offered in three levels, each requiring additional fueling upgrade hardware to produce higher levels of power output. This offers customers an easy upgrade path and doesn't force upgrade costs on different power level goals. 

All stage 3 variations require upgraded intake, turbo inlet (with hybrid compatible adapter or bolt flange), downpipe, and intercooler. Visit the product page for IE part number recommendations on all required hardware.

IE B9 Stage 3 TTE710, TTE810, & Pure750 Transmission Tune

STAGE 3 TCU: Matching transmission tune

The engine computer is only half of the equation when tuning for big power hybrid turbos. IE Stage 3 and Stage 3 Plus ECU tunes far exceed the factory-set transmission torque limit and require 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. 

IE Stage 3 transmission tune is a free update for existing IE Stage 2 TCU tune owners. Buying for the first time? Purchase IE Stage 2 TCU tune with your Stage 3 purchase. 


IE B9 Stage 3 TTE710, TTE810, & Pure750 horsepower

Now that you know what each variation of the three Stage 3 tunes are, what do they do? Each turbo has it's own characteristic, but they all lay down the power! Here is a quick max power output on the most popular octane for each stage for an easy comparison. 

For a full power report of every octane and complete dyno charts, please visit the product page and click on the performance tab.

TTE710 557HP / 565ft-lbs 578HP / 596ft-lbs 715HP / 678ft-lbs
TTE810 591HP / 601ft-lbs 613HP / 631ft-lbs 739HP / 705ft-lbs
 Pure750 589HP / 614ft-lbs 607HP / 637ft-lbs 739HP / 710ft-lbs


This chart compares the WHP/WTQ graphs of each different turbocharger against each other all running on IE Stage 3 Plus with E70 ethanol. Notice how all turbos have a very similar and fast turbo build up meaning the lag between the larger TTE810 and Pure750 is minimal compared to the smaller TTE710.

Audi B9 S4 S5 SQ5 TTE710 TTE810 Pure750 Stage 3 ECU Tune World Records

IE's history of pushing the envelope of power on Audi's popular B9 3.0T platform has cemented ourselves as software and hardware performance leaders with record-setting track success. Our Stage 3 Plus TTE710 development car is the first B9 to ever hit the 9-second quarter mile and still holds the overall B9 1/4th mile record with a 9.8-second at 140MPH run! The world's fastest customer-owned and second fastest quarter mile B9 S4 is currently a 10.08 set by Adam Blender with his IE Stage 3 Plus TTE710. Most recently, a new 1/4th mile record was set by David Musiyenko with an incredible 10.17 at 133.37MPH in his IE Stage 3 Plus TTE810 SQ5 SUV!

If you want a fast Audi, IE delivers top-tier performance without sacrificing reliability that delivers exhilarating fun on the track and the street.

Audi B9 S4 S5 SQ5 TTE710 TTE810 Pure750 Stage 3 ECU Tune Calibration

We won't sugar coat it, this kind of power is very close to the limits of the stock engine internals. In order to make these tunes as powerful and fun as possible without crossing that line, IE's engineers installed various additional sensors and probes throughout the engine. These systems allow our calibrators to properly configure the ECU by recording critical data that is unavailable 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.

IE B9 Stage 3 TTE710, TTE810, & Pure750 Hybrid ECU Tune 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.
