    F80 M3 with forged rods and pistons plus Gintani S55 crank hub fix making 737 rwhp with Pure Stage 2+ turbochargers

    This is the proper way to do it. Yes, you can do well over 700+ wheel horsepower on factory S55 internals. It's just a question of for how long. This owner upgraded his pistons and rods plus added the Gintani S55 crank hub fix kit for peace of mind.

    Mod list:

    - Custom tune
    - Pure Stage 2+ turbos
    - Fuel-It! Port injection and LPFP
    - Gintani crank hub fix kit
    - Pauter rods and Wiseco pistons
    - Upgraded DCT clutches

    737 rear wheel horsepower and 655 lb-ft of torque at the wheels:

    That is a great looking curve with power building all the way to the top.

    As for the fuel used, boost, and correction factor, @Peter @ Pure/PTF will need to chime in below in the comments.

    Do I read it wrong or does that torque curve look really bad?

    At that boost, it doesn't surprise me you get early valve float issues.
    New upgraded valve springs and you're golden.
