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, 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!

NOTE: While the S58 OEM injectors are a great budget pairing for the DS25, the DS3 requires even larger injectors to operate at it’s full potential.

Software changes are required to run this pump. If using Bootmod3 or MHD, simply check the box for our pump upgrade when flashing. Otherwise, please send your .BIN file to [email protected] for the appropriate software implementation via WinOLS.

NOTE: Higher flowing injectors are required to take advantage of the full potential of our HPFP. With just our HPFP (without our upgraded cam lobe) the best bang for your buck is the OEM S58 injectors. These provide +30% MORE flow versus the stock injectors.

Beyond the pump performance, why choose Dorch Engineering?

• PLUG AND PLAY: This is the ONLY true plug and play OEM fitment option on the market. Our kit includes our 350 bar capacity hardline to effortlessly connect our HPFP to your fuel rail (versus the time consuming process of bending and potentially 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.
