    • B9 Audi RS4 and RS5 hybrid turbo upgrade courtesy of Pure Turbos

      There is not a whole lot going on in the 2.9 liter twin turbo Audi EA839 V6 world. The B9 Audi RS4 and RS5 engine control unit (ECU) remains cracked and tuners do not have access. That is not stopping hardware development though.


      Pure Turbos has a Stage 1 hybrid turbo upgrade for the platform. They are stating wait for numbers but how exactly will one tune this?

      Maybe a similar approach as to Eurocode, SRM, and BMS on the B9 S4/S5 EA839 3.0 platform with piggyback tuning?

      Hopefully the RS4 and RS5 get going before the competition passes them by.
