    • BMW F22 M235i N55 making 587 horsepower direct injection only on E35 courtesy of Xtreme-DI upgraded HPFP and Pure Turbos Stage 2

      The biggest development in BMW direct injection fuel system tuning is the upgraded HPFP (high pressure fuel pump) from Xtreme-DI. They have single and dual HPFP upgrades available depending on your setup and TTFS sells and provides software tuning for the pumps.


      This is a European F22 M235i put together by P-Connection. Here is the mod list:

      Cooling by Wagner Tuning
      Flasher by MHD Tuning
      Upgraded HPFP by Xtreme-DI by TuningTech FS
      Stage 2 Turbos by Pureturbos.eu
      Two disc clutch with steel EMS

      Here is the result:


      You can see 587 horsepower is crank output but they just cleared 500 whp with the Pure Turbo Stage 2 turbocharger on E30 with direct fuel injection only. No methanol, no port injection.

      The HPFP upgrade from Xtreme-DI sure seems like the real deal with successful applications across multiple platforms.
