From the creators of the world’s first B58 direct-injection fueling upgrades, comes our next generation of pumps. Our widely successful “Dorch Stage 2” (DS2) has been replaced with our latest and greatest creation; the DS25! This new pump is our “Stage 2.5” which has been completely redesigned and optimized from the ground up. Externally we’ve updated the packaging 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, we’ve re-worked the pressure chamber, spring rates, plunger depth, and completely optimized the volumetric efficiency of the pump.
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 our pump upgrade when flashing. Otherwise, please contact sales@urotuning.com for further assistance.
Beyond the pump performance, why choose Dorch?
- PLUG AND PLAY: This is the ONLY true plug and play OEM fitment option on the market. Our kit includes our 250 bar capacity hardline to effortlessly connect our HPFP to your fuel rail (versus the time consuming process of bending and damaging the OEM line to fit).
- LIFETIME WARRANTY: The reason we can offer this is simply because our pumps are THAT reliable. That said, on the slim chance you have an issue, we’ve got your back!
- CUSTOMER SUPPORT: Ask around! It’s no secret that we offer unrivaled 24/7 support with REAL help. You’re an email away from professional engineers, technicians, and our tuner, who can solve anything you throw at them.
- TUNING SUPPORT: We aren’t just a hard part’s manufacturer. We have a dedicated calibration engineer in-house who painstakingly develops all of our HPFP files using OEM calibration tools and supports a global tuning network.
