IE Stage 3 TTE710 offers an easy upgrade into hybrid turbo power levels delivering up to 601HP and 615TQ from pump fuel (91, 93, or 104 octanes) with only the turbocharger upgrade along with stage 2 hardware (intake, turbo inlet, intercooler, & downpipe). This setup delivers deceivingly fast performance on stock MAP sensors and without additional fueling upgrades.

IE Stage 3 plus is for those looking to smash the competition with the maximum power output available from the hybrid turbocharger. This blistering fast calibration requires additional hardware upgrades to increase fueling support for even more power from pump gas and unlocks ethanol blends. Using an upgraded HPFP (high pressure fuel pump) and TTE 4 bar map sensors for up to 642HP and 638TQ on E30 ethanol blend. Or go all out with a truly exhilarating 715HP and 678TQ with upgraded fuel injectors and E70 ethanol blend!

IE Stage 3 and Stage 3 Plus far exceed the factory set transmission torque limit while delivering more power across the entire powerband and holding that power further into the higher RPM range. These performance enhancements require a complete matching transmission control unit (TCU) calibration. IE Stage 3 TTE710 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 engineers and calibrators valued fast boost response, top-end power, and a robust build when selecting a turbocharger as the base for our Stage 3 tuning. After extensive research and testing, the clear winner by a long shot was the advanced design of the German-made TTE710 from The Turbo Engineers. This hybrid turbo is a direct bolt-in replacement that provides a unique combination of big top-end power and responsive boost with very minimal lag. When combined with IE's calibration strategies, the result is a perfect marriage of modern vehicle tech and raw chest-pounding performance.

TURBO SOLD SEPERATELY

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 TTE710 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.

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.

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 TTE710 engine management system completely realized within the factory ECU.

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 the TTE710 from the ground up, ensuring proper drivability, perfect boost control, safe boost regulation, and guaranteed consistency in all driving conditions.

The vast difference in wastegate flow and response with the TTE710 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.

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 tune variant set the B9 3.0T world record and became the official first B9 3.0T in the 9s!

Stage 3 Plus utilizes 4-bar MAP sensors and an HPFP upgrade to open the fueling potential for the E30 ethanol blend for a massive jump in power over pump gas. Upgrade your fuel system with optional 4.0TT RS injectors for a higher E70 blend and the track-destroying 715HP! E30/E70 is the highest blend safely available within the fuel system limitations delivering the maximum performance numbers without pulling power for higher E%. Ethanol content must not exceed 5% of the required blend; an ethanol content sensor kit and gauge are highly recommended.

Brake Boosting provides a competitive edge in a roll racing scenario by using brake pressure to build boost at speed resulting in a rolling launch.

Brake Boost is included on Stage 3 & Stage 3 Plus

Stage 3 files include optional exhaust overrun/crackles for an aggressive motorsport sound during decel or free-revving in neutral or park. The feature is enabled in sport mode only and can be disabled by setting drive select to comfort, or toggling engine sounds to comfort in individual mode.

Exhaust Overrun is included on stage 3 and Stage 3 Plus.

The larger turbocharger requires increased airflow from an upgraded air intake system. Additionally, the TTE710 has an increased 66mm turbo inlet size at the compressor requiring a matching aftermarket turbo inlet. IE intake and turbo inlet are recommended to make the installation process of your new hybrid turbo a simple bolt-in job. Our cast turbo inlet design utilizes a CNC-machined adapter to fit the TTE710 without hassle while maintaining the largest size possible for zero flow restrictions.

With power comes heat; upgrading your intercooler is crucial for both performance and safety on TTE710 Stage 3 power levels. Our IE FDS Intercooler upgrade is highly recommended to provide the lowest IATs from unique design features and proven charge-air cooling capability.

The factory-equipped downpipe cannot support the power levels provided by IE's Stage 3 race suite and the hybrid turbo's exhaust flow rate; a performance aftermarket downpipe is required. Our TTE710 development vehicle was equipped with this downpipe in our world-first 9-second B9 3.0T quarter-mile run. Our IE Cast Catted Downpipe Kit provides a direct-fit install with the hybrid turbo.
