Real-world numbers back this up directly: paired with larger injectors and Dorch's Stage 1 pump, this supports \u003cstrong\u003e750whp on E10 and 600whp on E85\u003c\/strong\u003e. Paired with larger injectors and their Stage 2 pump, it climbs to \u003cstrong\u003e900whp on E10 and 750whp on E85\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eImportant compatibility notes:\u003c\/strong\u003e this lift kit is genuinely \u003cstrong\u003enot compatible with OEM HPFPs\u003c\/strong\u003e, it must be combined with one of Dorch's existing upgraded N55 HPFP kits (DS1\/DS15 or DS2\/DS25). When paired with the DS2\/DS25 pump, a minimum power requirement applies, this is simply to keep the tune manageable for your tuner. There's no minimum requirement when paired with the DS1\/DS15 pump, making that combination sensible by default for most builds.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eSoftware changes are required to run this upgrade\u003c\/strong\u003e, not optional, though preset optimised maps are available via Bootmod3, with MHD support coming soon, simply select the appropriate \"Lift Kit\" option when flashing.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e \u003c\/p\u003e\n\u003ch2 dir=\"ltr\" class=\"mt-2 -mb-1 text-base font-bold\"\u003eWhy Choose This HPFP Upgrade\u003c\/h2\u003e\n\u003cul dir=\"ltr\" class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3 print:block print:space-y-1\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e+49% more fuel flow on top of an existing Dorch N55 HPFP kit\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eSupports up to 900whp on E10, or 750whp on E85, with Stage 2 pump and larger injectors\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eGenuine BMW vacuum pump cores with Dorch's proprietary cam installation\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eRetains full OEM DME safety and sophistication\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003ePreset Bootmod3 maps available, MHD support coming soon\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2 dir=\"ltr\" class=\"mt-2 -mb-1 text-base font-bold\"\u003eCompatibility\u003c\/h2\u003e\n\u003cul dir=\"ltr\" class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3 print:block print:space-y-1\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBMW F20\/F21 M135i (N55, EWG, built after ~07\/2013)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBMW F22\/F23 M235i (N55, EWG)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBMW F30\/F31\/F34 335i\/335xi (N55, EWG, built after ~07\/2013)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBMW F32\/F33\/F36 435i\/435xi (N55, EWG)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBMW F10\/F11 535i\/535xi (N55, EWG, built after ~07\/2013)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBMW F25\/F26 X3\/X4 35i (N55, EWG, built after ~07\/2013)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBMW F87 M2 (N55, EWG)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eNot compatible with:\u003c\/strong\u003e OEM HPFPs (this is an add-on to an existing Dorch upgraded HPFP kit, not a standalone product).\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eHow to confirm EWG vs PWG:\u003c\/strong\u003e production date determines this, not model year.
