We’ve been tuning Jonatan’s MazdaSpeed3 from Sweden for some time using VersaTuner. It has a big turbo (GT3071) on the stock motor with a host of supporting modifications. He’s currently running E85 and sitting at 21-22psi but putting down some very impressive numbers and kicking butt at the track (watch him pass the Ferrari in the video below)!

Great Job Jonatan on the awesome car and build!
