From the creators of the world’s first B58 direct-injection fuelling upgrades, comes Dorch Engineering’s next generation of pumps. Their widely successful “Dorch Stage 2” (DS2) has been replaced with the latest and greatest creation; the DS25! This new pump is Dorch’s “Stage 2.5” which has been completely redesigned and optimized from the ground up. Externally, the packaging has been updated to provide exact OEM hose routing for ZERO interference when changing out coil packs or spark plugs. There’s no cutting, no bending, no crimping, etc. This kit drops right in with full control from the DME, just like factory. Internally, you’ll find a re-worked pressure chamber, spring rates, plunger depth, and completely optimized volumetric efficiency.

What does this mean? It means the most reliable and highest flowing B58 pump on the market just got even MORE reliable and even MORE flow! The DS25 is also designed to run efficiently all the way up to 250 bar in order to maximize the flow potential of upgraded DI injectors.

Software changes are required to run this pump. If using Bootmod3, MHD, or MG Flasher, simply check the box for this pump upgrade when flashing. Otherwise, please send your .BIN file to tuning@dorchengineering.com for the appropriate software implementation via WinOLS.
