Dorch Engineering DS3 High Pressure Fuel Pump HPFP - BMW F20 M140i | F22 M240i| F30 340i | F32 440i (B58)

After significant R&D, we’re proud to release the highest flowing single pump solution on the market, the DS3 (Dorch Stage 3)! This is our largest bore size and highest flowing pump to date, supporting incredible power with just a simple HPFP swap.  The DS3 is the same reliable, OEM drop-in solution you’re used to, but with 20% more fueling gains than our DS25! As usual with our kits, we have OEM hose routing for ZERO interference when changing out coil packs or spark plugs. There’s no cutting, no bending, no crimping, an included OEM quality high pressure line, etc. This kit drops right in with full control from the DME, just like factory. Combine this with our game changing injectors and one of our cam solutions and you’ll have never before seen, 4 digit direct-injection power!

Software changes are required to run this pump. If using Bootmod3, MHD, or MG Flasher, simply check the box for our pump upgrade when flashing. Otherwise, please send your .BIN file to tuning@dorchengineering.com for the appropriate software changes. This change is free of charge for all of our customers.
