    • Audi B9 S4/S5 3.0 TFSI EA839 turbo upgrade coming from Pure Turbos with JB4 tuning - Pure Stage 2 B9 S4

      The EA839 V6 ECU whether in the B9 R4 or RS4 is not yet cracked. That said, BMS has been helping various turbo builders with tuning using their JB4 piggyback on the platform to get turbo upgrades working.


      Pure Turbos is offering a Stage 2 turbo upgrade for the B9 S4/S5 3.0 V6 twin scroll and it is much, much larger than the factory compressor:


      What will the result be? How much power? Hopefully BMS shares more details on this build soon.

        I understand, that's why I put it on my instagram story while I'm working on the car. We'll have some results soon hopefully at NFZ with a stock turbo S4 and this Pure S4.

        This is good news not only that Pure has a turbo option but that you guys are working on a tune.

        Looking forward to the results! I expected this to be a hot platform but the ECU has held it back.
