407HP VW TSI GT3071r Turbo Unitronic Stage 3

Full Article with pictures: This unique TSI engine is currently pushing 400HP @ 20 PSI on a stock fueling system! Once the High-Pressure Fuel Pump (HPFP) and injectors are upgraded, it will blast about 500HP @ 25PSI without w/m. This is the only GTI TSI in North America running a GT30 Big turbo Unitronic Stage 3! The upgraded parts are in their prototyping stage and we hope to soon see them on this Volks.
