Dorch Engineering DS25 HPFP Upgrade (Gen 2 B58)
£2,315.96
From the creators of the world’s first B58 direct-injection fueling upgrades, comes Dorch Engineering’s next generation of pumps. They’re proud to announce the 350 bar version of the already wildly successful DS25 pump; another first of it’s kind in the aftermarket! Internally, the entire pump body has been reworked along with new spring rates, plunger depth, and completely optimized volumetric efficiency. What they’ve come up with is the same consistent and extremely reliable HPFP solutions they’re known for, but now at 350 bar operating pressures for Gen2 B58 compatibility! There’s no cutting, no bending, no crimping, etc. This kit drops right in with full control from the DME, just like the OEM pump. All of the safety and sophistication of the stock DME remain in place.
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.

Beyond the pump performance, why choose Dorch?
- PLUG AND PLAY: This is the ONLY true plug and play OEM fitment option on the market. The Dorch DS25 kit includes a 350 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 Dorch can offer this is simply because their pumps are THAT reliable. That said, on the slim chance you have an issue, they’ve got your back!
- CUSTOMER SUPPORT: Ask around! It’s no secret that Dorch 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: Dorch aren’t just a hard part’s manufacturer. They have a dedicated calibration engineer in-house who painstakingly develops all of their HPFP files using OEM calibration tools and supports a global tuning network.
