The TTE1020 Hybrid Turbocharger Upgrade for the 4.0TFSI EA825 found in the C8 Audi RS6 and RS7 is capable of up to 936 HP / 830 LB-FT combined with Unitronic Stage 3 ECU Performance Software, Unitronic Stage 3 TCU Performance Software, Unitronic Stage 3 TCU Performance Software and supporting Unitronic Hardware upgrades.

The TTE1020s are remanufactured factory turbochargers, with TTE fitting larger billet compressors and 9-blade exhaust turbines, with the appropriate milling of the exhaust housing to suite greater power capacity. Precise balancing of the TTE turbochargers is a key critical factor to becoming a TTE upgrade unit, as longevity and performance are paramount. Good balance improves acoustics; subsequently, great care is taken with all TTE turbochargers to achieving the TTE balance standards.

Firstly parts are balanced at slow speeds up to 2800RPM in multiple planes using TTE's esingle parts machine, then components are assembled, and then the CHRA's are dynamically balanced, but this time depending on the application, at up to 250,000 RPM in multiple planes using its in house VSR machine to acquire the ultimate equilibrium, to a standard far higher than OEM. Each turbocharger is supplied with a serial-numbered balance test result document.
