In this video, we take a deep dive into our latest MK6 GTI development and lay out a complete recipe for building a responsive, streetable 500 WHP MK6.
At the heart of the setup is the Stratified MK6 turbo upgrade, capable of supporting 500+ WHP while delivering full boost around 3,500 RPM. We wanted a turbo that didn't force you to choose between response and top-end power — because a great street car needs both.
But airflow is only one side of the equation.
We're also introducing the latest evolution of our MK6 auxiliary fueling system: twin port injection. With two additional port injectors, we've expanded the fueling capability available to support higher-output builds and ethanol fuels while retaining the flexibility and control we want from a properly engineered fuel system.
Then we bring it all together with calibration flashed using the @cobbtuning Accessport and @HPTuners for the DSG.
Turbo sizing, fueling, boost control, engine management and supporting hardware all need to work as a system. In this video we explain the hardware, show you how it performs, and walk through our approach to building an MK6 capable of reaching the 500 WHP level without turning it into a compromised dyno car.
We've been developing, tuning and supporting the MK6 platform for years. This package takes everything we've learned and applies it to what we think a modern high-output MK6 should be:
500+ WHP capability.
Full boost by ~3,500 RPM.
Twin port auxiliary fueling.
Street-focused response and drivability.
One complete, proven approach.
The MK6 may not be the newest GTI anymore, but we're definitely not finished developing it.
