This is genuinely their largest bore size and highest-flowing pump to date, supporting incredible power potential with just a simple HPFP swap, delivering \u003cstrong\u003e20% more fuelling capacity than the DS25\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eIt remains the same reliable, OEM drop-in solution you'd expect from Dorch Engineering, no cutting, no bending, no crimping, with an included OEM-quality 250-bar high-pressure fuel line. This kit drops right in with full control retained from the DME, exactly like the factory pump. A genuinely useful detail carried over from the DS25: OEM hose routing means zero interference when changing coil packs or spark plugs. The numbers: \u003cstrong\u003e860whp on gasoline, 725whp on E50, 630whp on E85 at the DS3 alone (250 bar)\u003c\/strong\u003e, climbing to \u003cstrong\u003e1150whp gasoline, 1000whp E50, 870whp E85 when paired with a 40% cam upgrade\u003c\/strong\u003e, matching the same ultimate ceiling as the Gen 2 platform via a different operating pressure and cam ratio.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eCombine this with Dorch's own injectors and a cam solution, and this genuinely opens the door to never-before-seen, 4-digit direct-injection power.\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 pump.\u003c\/strong\u003e If using Bootmod3, MHD, or MG Flasher, simply select the pump upgrade option when flashing.
