Welcome to the home of the highest powered direct injection N55 cars on the planet! 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!

This is the perfect track-proven solution for those who need more than the DS25 can offer, but don’t quite want to commit to the cost and installation effort of our N55LK combo.

Just like ALL of our HPFP kits, 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 MHD or Bootmod3, simply check the box for our 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 kit is truly 100% plug and play OEM fitment. Our kit is equipped with everything you need, including our 250 bar capacity hardline to effortlessly connect our HPFP to your fuel rail.
• 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.
